3, the valve is unique to three adjustable packing structure, to ensure that the valve cover and valve stem seal is reliable. Flange connection size according to JB/T79, can also according to customer requirements specified standard production.
Need for 4 pipeline pigging, diversion hole plate valve plate valve without diversion hole without Pigging for pipeline pigging on.
5, the valve body cavity pressure rises, the valve seat can be automatically discharged back pressure.
6, the valve drive mechanism to ensure that the valve opening and closing flexible, and its opening and closing torque is only 1/3 ~ 1/2 of the ordinary valve.
7, pneumatic gate valve opening and closing rapidly, with a buffer, and closed without impact, pneumatic, manual conversion structure is novel, flexible operation, convenient and reliable.
8, adjustment type flat plate gate valve is suitable for the pump, the station outlet and other need to adjust the medium of the pipeline, adjust and cut off the medium.
9, the valve can be widely used in petroleum, natural gas, chemical industry, environmental protection and other pipelines, oil and gas venting system and storage device, convenient and reliable.
10, the company also produced the same type of regulation and other special requirements of the flat gate valve.
11, the electric flat gate valve is generally used in Yangzhou power equipment repair factory?or?two Tianjin electric head, also can according to user needs matching UK Rotork (IQ Series), German Omar Aull (SA Series)?or?by the customer in the domestic electric head with any manufacturers moved.
