BSZ641 Pneumatic flanged gate valve

Advantage：large stock in common models,special models could be custom-made!

Details

The state song's BSZ641H pneumatic gate valve has the characteristics of reliable performance, convenient operation and repair switch. Petroleum, chemical, has been widely used in all kinds of marine sectors such as media control. Pneumatic gate valve with pneumatic actuator and manual mechanism, valve actuator with double cylinder structure, it is with a single cylinder type pneumatic valve, lifting force increased one times, solved some valve single cylinder type pneumatic valve in the valve body wedge die and not open, a buffer institutions, can effectively reduce the valve plate when the valve is closed by the piston down caused by the impact of the sealing surface and valve sealing surface wear, but also to avoid the Death Gate cards phenomenon. Gas back to the hearing moving flange gate valves can be equipped with electric or gas, used to transmit the valve switch state information. Can realize remote control, centralized control and automatic control. Pneumatic gate valve (with a top mounted handwheel) pneumatic gate valve (with side mounted handwheel)

Features

Fine material, in accordance with the relevant standards at home and abroad, the overall high quality materials. ||| Meet the requirements of domestic and foreign advanced standards, reliable performance, beautiful appearance, good sealing. ||| The sealing pair is advanced and reasonable, the sealing surface of the gate and the seat of the use of different hardness of Si Taili (Stellite) surfacing Gu Ji hard alloy and become, reliable seal, high hardness, wear resistance, high temperature resistance, corrosion resistance, good anti abrasion performance, long life. ||| Stem through the quenching and tempering and surface nitriding treatment, with good corrosion resistance, scratch resistance and abrasion resistance. ||| With flexible wedge gate structure, the large-diameter set thrust bearing, the friction force is small, and is equipped with impact manual, opening and closing the ease. ||| Can be a variety of standard pipe flanges and flange sealing surface in the form, to meet a variety of needs and user requirements.
