Description

PRODUCT RANGE: Sizes: NPS 1/4 to NPS 4 Pressure Range: Class 150 to Class 2500 Flange Connection: RF, FF, RTJ MATERIALS: Casting: (A216 WCB, A351 CF3, CF8, CF3M, CF8M, A995 4A, 5A, A352 LCB, LCC, LC2) Monel, Inconel, Hastelloy, UB6 Forged (A105, A182 F304, F304L, F316, F316L, F51, F53, A350 LF2, LF3, LF5,) STANDARD Design & manufacture API 6D, ASME B16.34 Face-to-face ASME B16.34, DIN 3202-M3 End Connection ASME B1.20.1,BS21,DIN 2999/259,ISO 228/1,JIS B 0203,ISO 7/1 Test & inspection MSS SP-110,EN 1226 Fire safe design API 6FA, API 607 Also available per NACE MR-0175, NACE MR-0103, ISO 15848 Other PMI, UT, RT, PT, MT Design Features: 1.Blow-out Proof Stem 2.Pressure Balance Hole in Ball Slot 3.Lock device 4.Various Thread Standards Available The 3-piece welded end ball valve can be closed tightly with only a 90-degree rotation and a small torque. The completely equal internal cavity of the valve provides a straight flow channel with little resistance for the medium. The main feature of the ball valve is its compact structure, easy to operate and maintain. The stainless steel ball valve can be used to control the flow of various types of fluids such as air, water, steam, various corrosive media, mud, oil, liquid metal and radioactive media. The valve body of the ball valve can be integral or combined. This type of valve should generally be installed horizontally in the pipeline. Stainless steel ball valve classification: stainless steel pneumatic ball valve, stainless steel electric ball valve, stainless steel manual ball valve. The 3-piece welded stainless steel ball valve is made of 304,316,321 stainless steel ball valves. 1. Open and close without friction. This function completely solves the problem of traditional valves affecting the sealing due to mutual friction between the sealing surfaces 2. Top loading structure. The valves installed in the pipeline can be directly inspected and repaired online, which can effectively reduce device shutdown and reduce costs. 3. Single valve seat design. Eliminates the problem that the medium in the valve cavity affects the safety of use due to abnormal pressure increase. 4. Low torque design. The valve stem with special structure design can be opened and closed easily with only a small handwheel valve. 5. Wedge-shaped sealing structure. The valve relies on the mechanical force provided by the valve stem to press the ball wedge onto the valve seat to seal, so that the sealing performance of the valve is not affected by the change of pipeline pressure, and the sealing performance is reliably guaranteed under various working conditions. 6. Self-cleaning structure of the sealing surface. When the ball is tilted away from the valve seat, the fluid in the pipeline will pass through the sealing surface of the ball uniformly at 360°, which not only eliminates the local washing of the valve seat by the high-speed fluid, but also washes away the accumulation on the sealing surface to achieve the purpose of self-cleaning .
