These valves are servo operated main valves with screwed-on pilot solenoid valves. These valves use an external pressure source for opening (which means that no differential pressure across the valve is required in order to maintain open state)
TSSV(TWO STEP SOLENOID VALVES)- Flanged conn. Size- (32 MM TO 125 MM)
These are 2 step servo controlled main valves with screwed-on pilot solenoid valves . These valves use an external pressure source for opening. (Which means that no differential pressure across the valve is required)
PATR(PRESSURE AND TEMPRATURE REGULATORS)- Flanged conn. Size- (25 MM TO 125 MM)
These valves are specially developed to regulate pressure and temperature in refrigeration, freezing and air conditioning plants with fluorinated refrigerants and ammonia.
