Torque of pneumatic control solenoid butterfly valve 1400? Ultra low temperature valve design standards: 1. Design: API6D, JB/T77492. Routine inspection and test of valves: API598. 2. Low temperature inspection and test of valves: according to JB/T7749. 3. Drive mode: manual, bevel gear drive and electric drive device. 4. Valve seat form: the valve seat is of welded structure, and the sealing surface is welded with cobalt base carbide to ensure the sealing performance of the valve. 5. The ram adopts elastic structure, and the pressure relief hole is designed at the pressure inlet end. 6. The one-way sealed valve body is marked with a flow direction sign. 7. Low temperature pneumatic butterfly valve, gate valve and globe valve adopt long neck structure to protect the packing.
、 Having said so much, I just want to let you know the composition and application of pneumatic butterfly valves. Otherwise, it is easy to buy valve devices that do not meet the actual conditions, which will affect the production efficiency.
