1) ZMQ / ZSQ series pneumatic shut-off valve is an actuating unit in the pneumatic unit portfolio instruments. It can auto control or adjust the medium's pressure, flow, temperature and level parameters by the control system.
2) This series has a simple structure, light weight, easy to use and maintenance, fire and explosion-proof, open quickly and assures no leakage, therefore, widely used in petroleum, chemical, metallurgy, pharmaceutical, paper making, printing and dyeing industry for the automatic control system during the production process.
3) This series of products conclude ZMQ type (pneumatic diaphragm shut-off valve series) ZSQ-III type (pneumatic piston-type shut-off valve) etc. PN (MPa) 1.6 \ 4.0 \ 6.4 \ 10.0 (ASME Class:150/300/400/600); DN (mm) 15-200 (1/2"~8″) ; leakage class: III /IV/ V/VI; This series has been widely applied in fluid vapor, flammable gases.
Zsho series of O shut-off ball valve
Zsho series of O shut-off ball valve have two-pieces type ball structure, which includes main and auxiliary two parts body, with advantages of resistant wear valve seat, high seal tightness, excellent shutting off function and long service life performance
With high rated flow coefficient and small flow resistance of full bore ball core structure, soft sealing valve seat sealing material is made by carbon fiber reinforced polytetrafluoroethylene
Hard sealing ball core and sealing ring surface has strong wear resistance by spraying tungsten carbide treatment
Valve seat is limit structure design, to maintain the torque stability, down to up steam mounted way to prevent it from flying out
Valve seat sealing ring with antistatic design and fire retardant performance
