Cycle Test Solution

Features and Benefits

• ASCO spool valve technology• Bypass feedback switch integration• Manual testing (during operation wthout interruption)• Verification of the functionality of the solenoid valve• Possible to change out faulty solenoid valve (during operation without interruption)• Temporary by-pass using special rotary key switch• Indication to control room when SOV is in By-pass• ATEX approved parts and solenoid valve• Flow rate for By-pass of 2800 L/m (1/4”, 1/2” size)• Unit designed and constructed by ASCO/NUMATICS• Simple and affordable• Panel Installation in SS 304L or SS316. Optional with Sunshade

Description

• Integrated system includes filter regulator, bypass module and solenoid valve• Manual bypass to test solenoid function

Application

• Critical actuator control for Oil & Gas, Refinery and Petrochemical processes with online diagnostic testing to increase reliability

Filter Regulator

• Option for protection filter regulator for cleaner air• Aluminium or SS 316L available • SAFETY CODE: II 2G/D c IIC X T85°C (T6) (ZONE 1-21) Explosion Group IIC• Body, bonnet and internal parts in 316L stainless steel in accordance to ASTM A 182/NACE MR 01.75• Different grade of filtration available upon request• Automatic drain, semi-automatic and manual drain

Bypass Unit

• Hot Bypass for Solenoid Testing• Build of anodized aluminium block • Three positions switch: Normal, Test Solenoid, Maintenance - Normal Mode: During regular operation, the bypass valve is in the “Normal” position, which the solenoid valve pilots the bypass valve

- Test Mode : The bypass valve is put in the “Bypass” position to test the solenoid valve. The solenoid valve can then be safely tested to confirm the functionality of the solenoid valve. Its correct operation is confirmed by the pressure gauge.

- Maintenance Mode: With the Bypass unit, the mal-function solenoid valve could be replaced without affecting the main valve’s operation.

• 12 different construction available• Construction is unique and robust

Solenoid Valves

• Constructed with SIL 3 capable certified solenoid valves for Functional Safety• ASCO most reliable valve Series 327 1/4” & 1/2” and Redundant Series• Fittings & Tubing in SS316L• Quality tested with required torque tension• Also available with Manual Reset• Redundant Series recommended for fail safe pilot applications • When the redundant valve controls an actuator, the actuator remains in position as long as one of the two solenoid valves (coils) is energized. To exhaust the actuator, both solenoids have to be de-energized.

Feed Back Unit for Critical location

• Control room notified by the Bypass feedback unit• Contact switch SPDT NO + NC 1.5A• In hazardous zone, ATEX ll2 EExdllCT6, ll2D IP65 T80°C

ATEX ApprovalMany different solenoids are available to meet the different categories, pro-tection methods and environmental conditions. Solenoids valves comply with both the ATEX electrical and non-elctrical standard for gas and dust.

Functional SafetyPilot Valves are TÜV certified according to IEC 61508. Functional safety data is available on request. The pilot valves have SIL 3 capability. Low PFD figures contribute to an economical SIS loop.

Manual ResetFor safety reasons optional man-ual reset functions are available. When the power returns after a shutdown, the valve must be set to its normal safe position manu-ally. The manual reset enables an extra safety check to be performed.

Power ConsumptionThe special non sticking seals offer a very low friction. In combination with the balanced poppet contruction this reduces the power consump-tion. Various power ratings are avail-able to cover the different flow, tem-perature and safety requirements.

ReliabilityHigh reliability pilot valves and solenoids avoid spu-rious trips and guarantee high reliability even in a 1oo1 and 2oo2 configuration
