ZMQP pneumatic diaphragm cut-off valve
ZMQP pneumatic diaphragm cut-off valve, use top-guide structure, equipped with multi-spring actuator. Impact structure, light weight, flexible action, S-type fluid channel, little loss of pressure drop, large capacity of valve, convenient assembly
Cut-off valve receive signal from automatic regulation instrument, cut-off, open or change flow direction of media, achieve automatic control and remote control of petroleum, chemical, metallurgy, power, light industry, textile
This product contain two kinds: diaphragm, piston. Structure of valve body: single-seat, sleeve, double-seat(two-bit three-way), sealing type: filler and bellows, nominal pressure PN10、16、40、46, nominal diameterDN20~200mm. Suitable temperature: -60~450℃, leakage: IV level or VI level, flow characteristics: quick open
Product features
Multi-spring actuator connected to adjusting actuator with three-joints stand, whole height reduced 30%, weight reduced 30%
Valve body designed according to mechanics, rated flow coefficient increased 30%
Internal components of valve: strict and soft sealing, strict is surfacing carbide, soft sealing is quality materials
Balanced internal components, improve allowed pressure difference of cut-off valve
Bellows-mobile valve stem, form complete sealing, prevent leakage of media
Piston actuator, large operation force, large using pressure difference
