g. Zmq/zsq series control valves:
zmq / zsq series pneumatic shut-off valve
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.
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.
?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.
types of zmq/zsq:
* zmq-type pneumatic diaphragm shut-off valve, valve plug in the form of zmqp (single-seat pneumatic diaphragm shut-off valve), zmqm (pneumatic cage shut-off valve), zmqn (pneumatic double-seat shut-off valve), zmqpv (pneumatic bellows seal single-seat shut-off valve), etc. (figure 1, 2, 3, 4, 5)
* zsq-iii pneumatic piston shut-off valve, the working temperature (-40 ~ 450celsius). Plug in the form of zsqp (pneumatic piston single-seated shut-off valve), zsqm (pneumatic piston cage shut-off valve), zsqn (pneumatic piston double-seated shut-off valve). (figure 2,3,4,5).
