Feature:SHANGHAI AUTOMATION INSTRUMENTATION CO., LTD

pneumatic low-temperature control valveDetails:

ZMAP-16D pneumatic low-temperature control valve
Pneumatic diaphragm low-temperature adjusting valve, is the improved product based on single, double-seat adjusting valve. Use long-necked upper cover, make filler work under normal temperature. Used for regulating media(like liquid oxygen, liquid nitrogen), temperature in -60~-250℃. For ensure regulation precision, should equipped with a valve positioner
Structure principle
Pneumatic low-temperature adjusting valve, made up of pneumatic diaphragm actuator and anti-low-temperature single, double-seat valve
Signal pressure from regulator, input into air room of pneumatic diaphragm actuator, produce thrust, drive valve spool, position of valve spool changes,  then change the flow cross-sectional area, then can regulate the flow of meida
