Z61H since seal pneumatic valve forged steel gate

useful since the pneumatic sealing forged steel gate valve product overview
useful since the seal design and manufacture of pneumatic valve forged steel gate in compliance with API and ASMEB. 。 Inspection and testing according to API, mark according to MSS - SP- 。 Use the following structure light pole scaffolding full size or reducing ( OS& Y） Since the centering clamp pressing sleeve type bolt connection design and manufacture in accordance with API and ASMEB. 。
useful since the pneumatic sealing forged steel gate valve product advantages:
, small fluid resistance, sealing surface Chong brush and erosion by the medium.
, open and close more effort.
the flow direction of medium, not restricted, disturbed flow, reduce the pressure.
, the structure of the form is simple, short length, good manufacturing technology, wide application scope.
useful since the pneumatic sealing forged steel gate valve disadvantages:
, easy cause erosion and abrasion, surface maintenance more difficult.
, shape size is larger, open needs certain space, open and close time is long.
and complicated structure.

the installation using the pneumatic sealing forged steel gate valve:
, before installation shall check the pneumatic valve cavity and seal face and other parts, there is no dirt or sand clinging to the body;
, each bolt connection parts, even tight;
pressure and check the packing requirements, both to ensure that the packing sealing, also to ensure that the gate is open and flexible;
, user before installation of pneumatic valves, pneumatic valves must be checked model, connected to the flow direction of medium size and note, ensure consistency with pneumatic valve requirements;
, user when installing a pneumatic valve, pneumatic valve drive necessary space must be reserved;
and wiring shall be according to the circuit diagram of the driving device;
, brake pneumatic valve must be regularly maintenance, shall not be arbitrarily collision and extrusion, in order to avoid affect the sealing.
