Description
1. Middle cavity of valve adopts hte pressure sealing strucuture, the high medium pressure, the better sealing property.
2. Two end of branch pipe is welding connection. It is suitable for different connection requirement.
3. The withstand pressure parts of valve chooses the excellent alloy steel. It has the advantages such as good high temperature performance, high bearing pressure, safe and reliable property.
4. Sealing face of valve flap and valve base adopts the STL cobalt base hard alloy welding to form. The sealing face hardness is high and it has advantages of anti-abrasion, anti-high temperature, anti-corrosion, scraping proof and long service life.
5. Valve flap turns around the pipe out valve base. It can reduce the impulse when closing.
6. Pin structure is installed inner. It can reduce the leakage.

Flange connecting end: ASME B16.5/ASME B16.47 Butt welding connecting end: ASME B16.25/ ASME B31.8 Fireproof test: API 607/API 6FA Inspection and test: API 6D Pressure and temperature rating: ASME B16.34 Product scope: NPS 1-1/2″~NPS 60″, CL150~CL2500 Main body material: WCB, LCB, WCC, CF8, CF8M, etc. Valve seat material: PTFE, RPTFE, NYLON, DEVLON, , PEEK, etc. Drive device: Handle, worm wheel, electric, pneumatic, etc. Main Feature Urgent grease injection device According to customer s' requirement, the trunnion ball valves made by our company are provided with devices for urgent grease injection, which are on both the stem and seat for the trunnion ball valves of DN >150mm (NPS), and in the body cavity for the valve of DN < 125mm. When the O ring of stem or the body seat ring is damaged due to accident, the medium leakage between body and stem can be prevented by injecting the sealing grease through the device. Double-block and bleed functions In general, our company's trunnion ball valve features the front ball sealing design structure. Each seat of the ball valve can separately cut off the medium at both inlet and outlet of the valve to realize double-block functions. When the ball valve is closed, body cavity and two of the body ends can be blocked with each other even if both the inlet and outlet are under pressure, when the medium left in the body cavity might be bled through the relief valve. Fire safe design With the valve heated in a fire application, the non-metal material parts such as seat sealing ring of PTFE, O ring for the stem, and sealing gasket for body and bonnet, might be damaged due to high temperature. Our company's special design of auxiliary metal to metal or the graphite seal is provited fo rthe trunnion ball valve to effectively prevent both internal and external leakage of the valve. As required by customers, our company's fire safe design for the trunnion ball valve meets the requirement of API 607, API 6Fa, BS 6755 and JB/T 6899. Self-relief in the body cavity As the liquid medium left in the body cavity gasifies due to increased temperature, the pressure in the body cavity becomes abnormally higher, when the medium itself in the cavity would propel the seat and self-relieves the pressure to ensure the safety of valve.
