Blind valve

Product Overview

The blind valve is mainly composed of left valve body, right valve body, valve stem, gate plate, sealing ring, pneumatic push rod and other parts, and a rigid structure is composed of base and support column. The sealing part adopts stainless steel and rubber sealing ring, which has good sealing performance and long service life. The sealing ring is set on the ram, which is easy to replace when maintaining. The rubber sealing ring is inserted on the ram. The pneumatic push rod blind valve can be controlled by single remote control or multiple remote control via network. Under abnormal conditions, the valve can be operated manually.

Structural characteristics

1. The valve is composed of left and right valve body, fan-shaped valve plate, stainless steel bellows, driving device, clamping device and other parts;
2. The valve body adopts three-point locking fan-shaped valve plate structure;
3. Stainless steel and rubber seal ring are used in the sealing part, so the sealing performance is reliable, thus increasing the service life of the sealing ring. The sealing ring is set on the valve plate, which is convenient to replace the sealing ring during maintenance;
4. The actuator operates stably, opens and closes flexibly and acts reliably;
5. The screw nut pair is used for clamping, which has good self-locking performance;
6. The blind valve is equipped with stainless steel bellows, which has the advantages of strong expansion and long service life.
