Size:DN15-DN300
1, advanced seat: seat ball valve designed manufacturing experience for many years, the low friction coefficient, the operating torque is small.A variety of the seat material, wide adaptation.
2, the valve stem fly structure: set up the steps, at the bottom of the valve stem bottoms stem from inside the body, prevent the valve stem.
3, anti-static function: between the ball and body or stem the Settings of the anti-static spring, will be generated switch movement process of electrostatic export.
4, fire-proof structure: advanced refractory design, after the fire, the leak designed to be flexible graphite packing or stainless steel clamp graphite, satisfies the requirement of refractory, comply with the provisions of the API6FA and API607.
5, handle, use flat head stem, and handle the connection is not misplaced, thus ensuring the switch state is consistent with the valve handle instructions.To prevent misoperation with valve switch, the switch is open, seated position set a lock hole, to ensure that the valve is in the right place.
6, fire-proof structure: advanced refractory design, after the fire, the leak sealing elements forming a metal to metal seal after burning, comply with the provisions of the API6FA and API607.Strict for refractory, tight sealing parts using the flexible graphite packing and stainless steel clamp graphite gasket seal, ensure no leakage.(please specify when ordering: the whole type fire FB)
7, valve adopts both at home and abroad the most advanced support plate structure, improve the service life of the valve, reducing valve operating torque.Greatly prolong the service life of the valve.
