The 150LB ball valve, made of Duplex stainless steel 4A, has a special V port ball. The valve is particularly suitable for media containing fibers, tiny solid particles, slurry and so on.

The 1-1/2 inch globe valve, designed as per API 623, has a bomb-shaped body and a parabolic plug both of which optimize the smooth flow of the media. The valve is made of stainless steel and is equipped with a handwheel, easy to operate and maintain.

The 4 inch cryogenic ball valve, designed as per API609, has many parts equipped RPTFE --It has the lowest coefficient of friction and the best corrosion resistance of any known plastic material, so that the valve can handle quite extreme situations.

The forged steel ball valve is made of A105 body and 17-4PH trim with RTJ flange end and lever operation. This floating ball valve features reliable sealing performance and easy operation.

The changeover valve is combined by two valves that are different from nominal diameter--one is DN100, the other is DN150. A handwheel is put on the right side of the valve to help control the large WCB-made device. Designed as per DIN 3356, the valve is usually put in the oil industry.

The 2-piece floating ball valve, made in accordance with API 6A, has a design of reduced bore, fire safe design, anti blowout stem. With the RPTFE seat and PTFE O ring, the 4 inch WCB valve is certificate to serve you.

The 10 inch Dual-Plate WAFER Check Valve is made of WCB and is eligible to be put under pressure up to 30LB. All Dervos check valves are tested to API 598 and must meet or exceed all applicable API, ANSI and ASTM Standards.

Made of F316, the floating ball valve is designed under the code of ASME B16.34. The valve consists of two-piece body, floating ball, lever operation, with good reliable sealing performance and small torque.
