Stainless Steel Penumatic Gate Valve
Working Principle and Application
Pneumatic 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.

Working Temperature: -196℃ - + 560℃
Material: Stainless Steel, Carbon Steel, Alloy Steel, etc
Suitable Medium: Water, Steam, Oil, Nitric Acid, Acetic Acid, etc
Operation: Penumatic, Electric, Hand Wheel, Gear, etc
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. Stroke of the piston to the top of the top 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 hand wheel 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.
