Flowrox Pinch Valves

Flowrox pinch valves are ideal for shut-off or control applications that involve abrasive or

corrosive slurries, powders or granular substances. Our advanced flow control solutions meet

even the most demanding customer specifications. Flowrox valves improve our customers’

productivity by improving process efficiency and extending service intervals.

The operating principle of a Flowrox valve is simple. In the open position, the valve is at full bore with no flow restrictions thus making the valve an integral part of the pipeline. During closing, two pinch bars squeeze the sleeve shut on the centerline.

MODULAR DESIGN

Our modular valve design has three main components: the sleeve, the body and the actuator. The sleeve is the only part that is in contact with the process medium. The construction and materials of all three main components can be selected to suit most process conditions. Self-cleaning Flowrox valves provide 100 % tight shut-off even if solids have built up on the sleeve wall. When compressed, any crystallized particles flake off the sleeve surface and are washed downstream.

The standard range is from diameters 25 mm to

1000 mm, temperatures from -50 °C to +160 °C, and operating pressures from vacuum to over 100 bar.

We provide tailor-made flow control solutions precisely in accordance with the customer specifications.

TECHNICAL FEATURES

• 100 % Tight• Full Bore• Only the Sleeve is in Contact with the Medium

• Linear Control Curve• Centerline Closing• Flexible Sleeve

RESULTING IN PROCESS BENEFITS SUCH AS

• Self-cleaning• Trouble-free

Operation• Long Service Intervals

• Excellent Wear Resistance• High Corrosion Resistance• No Jamming or Clogging• Low Maintenance Costs• Reduced Cost of Ownership

METALLIC VALVE: As abrasive particles and metal collide, the collision energy is absorbed into the metal, thus constantly wearing the surface.

FLOWROX VALVE: When particles hit the sleeve surface, the energy is absorbed by the rubber and returned to the particle when it bounces back. This results in excellent wear resistance and long service intervals.

Manual Valves

The manual valves are equipped with a handwheel actuator. To ensure reliable operation,

the operating mechanism of the valve is totally enclosed giving full protection against dirt and

corrosion. A reduction gear is provided to ease the manual operation in larger diameter valves and

higher operating pressures.

BODY TYPES

ENCLOSED BODY

The enclosed body valve is the most common body type. Its enclosed design prevents premature sleeve deterioration and protects the sleeve from the environment, making it extremely safe to operate.

Enclosed body valves can be manufactured of cast iron, fabricated carbon steel, stainless steel, aluminium or plastic. Valve diameters begin from 25 mm.

Manual Valves in Energy Industry

Products: 31 pinch valves, sizes 200-250 mm Medium: Ash Slurry

DONG Energy, one of the largest coal power plants in Denmark, has gained valuable benefits with Flowrox valves in their boiler ash/slag slurry installation. In the application, boiler ash/slag is grinded, mixed with sea water and then pumped into settling ponds. In 1996, a total of 31 Flowrox pinch valves were installed in the application. This abrasive and aggressive slurry sets high requirements for on/off slurry valves, and Flowrox pinch valves have more than fulfilled them.Benefits for the customer include excellent wear resistance, reliable operation and extended sleeve lifetime.

OPEN BODY

The open body valve is designed for non-hazardous media, lower pressures and operating temperatures. This design isolates vibration and tolerates minor misalignments of the pipeline. It is also light-weight and easy to service.

Material options include fabricated carbon steel and stainless steel. Open body range starts from 80 mm in diameter.

Flowrox pinch valves at DONG Energy

Special body types are available for applications dealing with hazardous media.

Automatic Valves

The actuated valves are ideal when remote control is required. The type of actuator depends on

the operating pressure, availability of power sources and other process requirements.

Automatic Valves in Mining Industry

Products: 400 pinch valves, sizes 25-200 mm Medium: Iron concentrate & pellet coating slurry

Flowrox pinch valves were chosen in 2008 when Gulf Industrial Investment Company (GIIC) was commissioning their second iron ore pelletising plant in the Kingdom of Bahrain. Flowrox pneumatically actuated PVE 100 – 150 mm valves are operating in pellet coating and iron ore slurry lines as well as in various side applications. The GIIC plant provides the highest quality pellets to markets all over the world.The best flow control solution was built in cooperation

PNEUMATIC ACTUATOR

The standard pneumatic actuator is double acting, therefore allowing fast opening and closing. Short cycle times are achieved by using quick exhaust valves.

Pneumatic actuators are suitable for a wide range of industrial applications. Epoxy paint can be applied to further improve

corrosion resistance. The actuators can be equipped

with an override hand wheel for manual fail-safe and a mechanical or pneumatic spring for automatic fail-safe function.

HYDRAULIC ACTUATOR

The compact, double acting hydraulic actuator is designed for applications where high closing forces or fast action are required (high operating pressure or large valve diameters).

ELECTRIC ACTUATOR

The standard electric actuator incorporates built-in limit and torque switches, as well as a manual override hand wheel. Electric actuators are well suited for

applications requiring high closing forces such as large valve diameters or high operating pressures.

SPECIAL ACTUATORS

Hydraulic actuators with an integrated power unit, pneumatic motor driven actuators, and water- hydraulic actuators are also available upon request.

CONTROL VALVES FOR DEMANDING DUTIES

Flowrox control valves are designed for demanding control applications in which conventional valves encounter problems with turbulence and wear.

Controllability can be further improved with conical sleeves or smart positioners. Elastic sleeves have been applied for improved wear resistance.

Flowrox has a control valve sizing program available for control applications.

PVEG Valves

The PVEG is a robust yet compact and light-weight pinch valve engineered with the highest quality

standards that Flowrox is known for. It is applicable in industries that require bubble tight shut-off

involving aggressive slurries, abrasion, corrosion, and pressure resistance.

PVEG Valves in Metal Recycling

Products: 15 PVEG valves, sizes 80-150 mmApplication: Pump and tank isolation in Dense media separation (DMS)

Early 2011, Flowrox PVEG valves were chosen by Sims Metal Recycling at one of their recycling plants in the UK. The light-weight manual operated PVEG valves are used to isolate pumps and tanks in their DMS plant. Flowrox products form a key part of Sims’ continued investments in the latest products and separation technologies, allowing them to recover maximum metal at minimum cost.

TECHNICAL FEATURES

• Enclosed body type• Size range: 50 mm, 80 mm, 100 mm, 150 mm• Working pressures: 0 to 10 bar (manual), 0 to 6 bar (actuated)• Temperatures: -50 °C to +70 °C• Body material: polyamide• Sleeve materials: SBRT, EPDM• Flange drillings: DIN PN10, ANSI 150• Air supply pressure for actuated models: min 6 bar• Auxiliaries for actuated models: magnetic limit switches, solenoid valve

The PVEG has a symmetrical two piece polyamide body that is both durable and cost efficient. It offers substantial savings through improved performance, longer service lifetime, and lower maintenance costs.

In many applications, the PVEG valves can easily replace often problematic ball, plug and diaphragm valves. When closed, the closing element squeezes the sleeve shut against the lower body half, providing a 100 % tight shut-off.

Flowrox PVG is a robust yet compact pinch valve engineered with the highest quality standards. It is made for processes involving pressure resistance, abrasion, corrosion and aggressive slurries. PVG offers substantial savings through improved performance, long service lifetime and low maintenance costs with pressure capabilities up to 10 bar.

COMPACT SOLUTION

In the open position, the PVG valve is at full bore with no flow restrictions. Therefore it is an integral part of the pipeline and anything running through the pipeline can also pass through the valve. PVG is designed to be reliable and compact solution for flow control. Being a full port design the valves require the least pumping energy and do not reduce system head pressure. Installation is trouble free and valve includes pre-installed rubber sleeves with opening tags, which withstand tough process conditions. This ensures long valve lifetime and minimal maintenance costs.

All these features add up to lowest total cost of ownership (TCO).

CORE OF THE VALVE The core of the PVG valve is its elastic sleeve, which is the only part in contact with the medium. Designed to withstand wear, corrosion and chemicals, Flowrox sleeves guarantee non-clogging, trouble free operation and extended lifetime. The sleeves are bubble tight and easily replicable if necessary.

Opening tags – ensures reliable operation

Outer layer – protects the sleeve

Reinforcement cords – gives the sleeve its pressure retraining capabilities

Inner layer – resistant to wear and chemicals
