Cast Steel Pneumatic Flange Gate Valve Z641H Product Overview:

The actuator of a pneumatic gate valve has two functions: forward and reverse, so the valve can be opened and closed in two ways: pneumatic opening and pneumatic closing. The gate valve adopts a metal contact structure, with reliable operation and high cutting performance, which is superior to conventional cut-off valves. Allow leakage to reach 10-8 × KV. The temperature can range from -196 ℃ to 500 ℃, with diameters as small as 40mm and as large as 600mm There are three types of valve seats: parallel, 60 ° V-shaped, and 90 ° V-shaped, which are suitable for different usage scenarios.

2. The valve body can be insulated in the form of a jacket, which is used in situations where the medium is prone to blockage, condensation, or coking after cooling.
