This series of valves have stable sealing performance, small opening and closing torque, sulfur resistance and wear resistance, long service life, can pass the hairball cleaning pipeline and other characteristics; Suitable for water, oil, natural gas, steam and other non-corrosive and corrosive media pipeline system as a opening and closing device, suitable for petrochemical, oil, gas, long distance pipeline and other fields.
 
 Features of flat gate valve with diversion hole:
1. Reasonable structure, tight seal, easy operation and maintenance.
2. Flat gate valve is divided into two categories of diversion hole and no diversion hole, the valve with diversion hole is used for the pipeline that needs to be cleaned by the ball, and the valve without diversion hole is used for the pipeline that does not need to be cleaned.
3. The gate and seat are treated with gold technology, spray welded cemented carbide, and the sealing surface is studded with PTFE, which has a double seal of PTFE to metal and metal to metal, and PTFE has the effect of scraping the gate dirt. And can be injected grease auxiliary seal double protection, tight seal, valve service life prolongation.
4. Compared with the traditional gate valve, the flat gate valve has the advantages of small switching torque, flexible opening and closing.
5. The valve has a triple adjustable packing structure, which can ensure tight seal with the valve cover and valve stem.
6. Regulating plate gate valve is used in pump, station outlet and other need to adjust the medium of the pipeline, adjust and cut off the medium.
7. The valve is equipped with a pressure relief device to prevent internal pressure and damage the valve, which can ensure the safe use of the valve.
Wb type no diversion hole flat gate valve reasonable structure, easy to blow down, not restricted by the scenting of the site, can be installed at any Angle.
9. Wp type flat gate valve light weight, small size, greatly reduce the pipeline load, suitable for oil, steam storage device.
10. Flat gate valve open and close quickly, with buffer mechanism, close without impact, pneumatic, manual conversion structure practical, flexible operation, convenient switch.
11. Our company also provides VT type, VS and other requirements of the plate gate valve.
Electric device can be selected according to user requirements of foreign and domestic manufacturers of products.
 
 Design and manufacture standard of flat gate valve with diversion hole:
Valve design and manufacture according to JB/T5298-91 and API6D regulations.
Valve structure length according to GB12221-89, JB/T5298 and API 6D regulations.
Flange connection size according to JB79, HGJ46, SH3406 and ANSI B16.5 provisions.
