■ Overview

The new series of pneumatic piston gate valves, hereinafter referred to as gate valves, are widely used in the industrial field due to their excellent cutting performance. The nominal pressure is 1.6 and 6.4 MPa, with diameters ranging from 40 to 600mm, and a temperature range of -196 ℃ to 500 ℃.

■ Characteristics

The actuator of a gate valve has two functions: forward and reverse, so the opening and closing methods of the valve include air opening and air closing. The gate valve adopts a unique metal contact structure, with reliable operation and extremely high cutting performance, which is superior to conventional cutting valves. Allow leakage to reach 10-8 × KV. Wide range of use, 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.
