Z6s41h Pneumatic Power Station Gate Valve - China

price: 300.00 Dollar US$

Product overview
Pneumatic gate valve, with the aid of compressed air driven valve, gate valve is closed, sealing surface can only rely on medium pressure to seal, that depend on medium pressure, the disc will be to the other side of the valve seat sealing surface pressure to ensure that the seal face seal, this is the seal.Most is adopt compulsory seal gate valve, the valve is closed, to rely on outside force forced the ram pressure to the seat, to ensure the sealing surface sealing
materials and instructions
1、This valve is mainly composed of valve body, valve cover, disc, valve stem, sealing ring, double cylinder and piston, piston rod, plate, together with the buffer mechanism, manual, pneumatic, manual switching device and cover packing device and other parts.
2、On the top of the piston top to trip on last time inquiry, make hair inquiry;The piston stroke bottom to the top of line down back to the device, make hair message, as gate valves open and close the information in the central control center simulation dashboard display.
3、The rise and fall of the upper part of the handwheel overhanging indication rod, marked the disc of the valve is in a state of ascension or falling.Gate valve is closed, overhanging indication rod in the lowest position;On the other hand, the gate is wide open, the overhanging indication rod is located in the highest position.This is the valve opening and closing state of the instructions.
4、The upper cylinder cover is equipped with pneumatic - manual switching device.Will transform the handle clockwise to "pneumatic" positioning hole position, gate valve in the pneumatic operation state;Conversely, convert the handle counterclockwise to turn to "manual" is due to hole location, gate valve can be manually.With bevel gear lever switch in the opposite direction.Manual gate valves, wheel spin and ordinary manual valve, namely clockwise to shut, counterclockwise to open.With bevel gear instead.
This valve can be with electric or gas back to the device, in order to send the valve switch state information.Therefore, the use of this valve can realize remote control, centralized control and automatic control.
Corrosion corrosion of cylinder, the valve cylinder selected for seamless steel pipe manufacturing, inner surface plating hard chromium in corrosion resistance, and the polishing process, the advantages of small friction, not easy to rust, high hardness, long service life, etc.
In the cylinder seals use nitrile butadiene rubber O ring, sealed performance is reliable, maintenance, easy to change.
