Slam Shut-off Valve

INTRODUCTION The slam shut-off valve model GIPS-FC is designed to quickly shut-off the gas flow when the monitored pressure exceeds the pre-set values, to protect the pipe line, the gas equipments and all downstream instruments from an unexpected over pressure or also in case of gas source interruption or even in case of rupture of it’s own tubing’s. Upstram Pressure Downstream Pressure Sensing Element (Diaphragm or Piston) Sensing upstream pressure Atmosphere Pressure It also has a fail-close function, that is, gas flow shut also occurs in the event of a rupture of the valve sensor element (diaphragm),...

WORK PRINCIPLE The GIPS-FC series valves have an actuator coupled by a Spheres Collar (1) which is connected to the Sensor Element (2) and monitors the downstream pressure. In cases of increase in operating pressure beyond the defined limit, rupture of the sensor element (diaphragm), rupture of the sensor line or operating pressure below the defined limit, the external bushing of the ball coupling (3) will be displaced and allow movement of the actuator shaft (4) and trigger a hammer blow, which will trigger the closing spring on the shutter locking system. In this way the blocking system is...

Actuator L, H, PH e TF For better accuracy and repeatability, the GIPS model block valve contains four different types of actuators, the L model, the H model, the PH model and the TF model. Downstream Pressure (sensing) Atmosphere Pressure GIPS FC - Pilot Operated Model (optional) If required, the GIPS FC model could be supplied in Pilot Operated model with the same accuracy and easy operation. GDPS Model - Actuator by Under Pressure (optional) The GDPS model slam shut-off valve has the same mechanism, precision and technical characteristics of the GIPS-FC model slam shutoff valve, but with exclusive...

Pressure Equalizer Valve (By-pass) The Pressure Equalizer Valve (By-pass) normally closed, it is applied on the GIPS slam shut-off valve to equalize the pressure between upstream and downstream of the shutter when the valve is in closed position, making resetting the tripping system possible. Button Model Lever Model Travel Indicator It is also possible to use it in a remote sensing system if combined with a position sensor type limit switch.

TECHNICAL CHARACTERISTICS Ap = P1-P2 [bar]; Q = Flow in [Nm3/h]; P1 = Inlet Pressure [bar absolute]; P2 = Outlet Pressure [bar absolute]; K = Pressure loss coefficient

TECHNICAL CHARACTERISTICS Notes: 1 - Actuator for GIPS-L is not fail close type. 2 - The Fail Close device for models GIPS-H and GIPS-PH are adjusted only in Gascat Plant. 3 - For special actuator versions that are not Fail Close type the DVGW approval is not valid and are not qualified in Class A of Standard DIN EN 14382. 4 - The following versions are not approved by DVGW: GIPS-L, GDPS and GIPS (H or PH) which actuator does not have Fail Close (FC) device.
