Valves

A valve with a flat or tapered gate that moves in a linear way over a seat to control flow Gate Valve

Cross Section Of a Gate Valve

Gate valves are designed to ensure a straight line flow and to reduce to a minimum the pressure drop due to friction. . Not recommended for throttling applications

It is very difficult for us to determine whether a valve is rising or non rising by just looking at the picture. So please do not assume if it is not mentioned in the description

Angle gate valve

Used for operating large valvesT-Handle (Valve Key)

Globe valve

A valve with one inlet and one outlet connection, consisting of a movable disc-type element and a stationary ring seat in a generally spherical shaped body.

Type/Style: Bolted Bonnet, Screwed in Bonnet, Union Bonnet, Flanged end, threaded end, Socket welded end, Two way valves ,Three-way valves.Body material: Brass, Gun Metal, Bronze, Cast Iron, Carbon Steel, Stainless Steel (SS) etcTemperature Ratings: 100*F,250*F etc.Pressure Ratings: 100PSI,250PSI etc.Pipe Size: 2,2-1/2NPT etc.

Ball valve

A non-lubricated valve for straight-through flow controlled by the rotation of a ported or eccentric ball upon a ported seat. The valve is quick opening with a 90 degree open/close radius.

Type/Style: Flanged end, threaded end, Socket welded end,1-piece,2-piece, 3-piece valves etc..

Body material: Brass, Gun Metal, Bronze, Cast Iron, Carbon Steel, Stainless Steel (SS), Plastic, PVC, Teflon etcTemperature Ratings: 100*F,250*F etc.Pressure Ratings: 100PSI,250PSI etc.Pipe Size: 1,1-1/2NPT etc.

Butterfly Valve

A valve utilizing one or two discs attached to a common spindle or lever to regulate flow.

Type/Style: Flanged end, threaded end, Welded, Clamped etc..Operation Type: Handle, Handwheel,Gear box, Electric Motor,Body material: Bronze, Cast Iron, Carbon Steel, Stainless Steel (SS), Plastic, PVC, Teflon etc Pipe Size: 2,3-1/2NPT etc.

Check valve/Non- Return Valve (NRV)

A valve that automatically limits flow in a piping system to a single direction.

Check valves are used to prevent the back-flow in a pipeline. The pressure of flowing fluid keeps the valve open, and any reversal of flow closes it. Swing Check Valve

Ball Check Valve

Plug valves

A quarter-turn valve with a straight or tapered, ported cylinder inserted into the flow path.

Type/Style: Flanged end, threaded end, Socket weld, Clamped etc.. Body material: Bronze, Cast Iron, Carbon Steel, Stainless Steel (SS), Plastic, PVC, Teflon etc Pipe Size: 2,2-1/2NPT etc.

Plug valve attributes

Needle valve

A type of valve where a tapered tip on the stem enters deeply into a stationary ring seat. Used primarily for throttling, (not for shut-off applications) and in tube/instrumentation type systems.

Needle valve

A valve designed to reduce the pressure of the fluid Pressure Reducing Valve (PRV)

Float valve

Thermostat

A device operated by the change in temperature of the liquid. It regulates and controls the liquid temperature by diverting the hot liquid to a radiator/cooler for cooling.

Pneumatic or Hydraulic Valves

Pneumatic Control Valve

Rotary (Pneumatic) Control Valve

An enclosure with externally driven multiple rotating vanes.

Cock Valve

A valve specifically designed with a tapered rotating plug which mates to a stationary tapered seat which allows flow from 0 to 100% in 90 degrees of motion. Commonly used in low pressure applications

Diaphragm Valve

A valve with an internal diaphragm that seals the flow stream from the valve operating mechanism. The flow is controlled by the diaphragm lifting from or compressing against a weir or protruding wall.

OpenThrottlingClose

Safety Relief valve/Safety Valve

A valve that automatically releases pressure beyond a specified limit and may or may not automatically re-close upon return to normal working conditions.

These valves can be installed without shutting off the main water supply. A saddle valve is a valve used to supply liquid where a low volume, low pressure liquid stream is required Saddle valve

Saddle valve

The valve with a connection facility to saddle over a line and to be bolted and having a line piercing facility. Flow is controlled by the action of stem.
