The valve consists of valve body, valve cover, gate, stem, seals, double cylinder and a piston rod, partitions along with buffering mechanism, manual, pneumatic - some manual conversion means and bonnet packing devices composition. Piston line to the upper stroke end may top on back to the hearing so that the sender; the stroke lower end of the piston line can under the roof next time hearing device, so that the sender, as the valve opening and closing the information in a central operations room of analog instrumentation It is displayed on the disc. Extended handwheel upper portion of the indicator rod rises and falls, marking the shutter of the valve is in a raised state or degraded state. When the valve is closed, the overhanging indicating rod at the lowest position; on the contrary, when the valve fully open, extended indicator lever in the highest position. Namely based valve opening and closing state of on-site instruction. Cylinder head unit equipped with a pneumatic - manual conversion devices. Converting the handle clockwise to mention go to the "pneumatic" positioning hole location, the valve is pneumatically operated state; conversely, converting the handle counterclockwise mention to "manual" is scheduled for hole positioning, valve can be manually operated. Instead handle change direction with the bevel gear. When operating valve manual hand wheel rotation and ordinary manual valves, like that in a clockwise turn off counterclockwise turned ON. With bevel gears opposite.

Z641W-16P / R / RL ~ 160P / R / RL stainless steel pneumatic valve is a pneumatic actuator (double cylinder, and with a shock-absorbing mechanism) and the manual and its protection mechanism (manual and self-locking pneumatic - manual conversion means ) lower bracket stem gate valve. The valve due to the use of double cylinder structure compared to single cylinder pneumatic valve, the lifting force increases doubled. This solves some of the valve body wedge death of a single cylinder pneumatic valve does not turn on the shortcomings fundamentally. Moreover, since the valve has a buffer mechanism, can effectively slow down the light when to close the valve, the piston downward impact caused by valve dray wear sealing surface and the valve sealing surface, but also can avoid brake board phenomenon of death .
