The valve stem of WZ41H corrugated pipe gate valve adopts a double sealing structure of corrugated pipe and packing, ensuring no leakage sealing at the valve stem, especially suitable for pipelines with flammable, explosive, toxic and valuable media. The sealing structure of corrugated pipes is designed reasonably, resistant to fatigue, and has a l1
Electric flange ball valve has the same 90 degree lifting action, with a circular through-hole or channel passing through its axis. The ratio between the sphere and the channel should be such that when the sphere rotates 90 degrees, it should all appear spherical at the inlet and outlet, thereby cutting off the flow.
The PZ673H pneumatic knife gate valve is a complex automation control instrument composed of various pneumatic components and valve bodies. Commonly used in situations that require quick cutting or opening. Dual function: Two position control for valve opening and closing; Single action: (Spring reset): In the event of electrical and pneumatic circ1
Stainless steel elbows need to be protected according to certain process measures during use and production, to protect the rationality and quality of castings. Production and processing should be carried out according to certain process techniques to protect the quality of stainless steel elbows. The stainless steel elbow is protected by a long no1
The Q41F soft sealed ball valve not only has a simple structure and good sealing performance, but also has a small volume, light weight, low material consumption, small installation size within a certain nominal diameter range. It also has a small driving torque, simple operation, and is easy to achieve fast opening and closing. It is one of the fa1
