Unique structure, flexible design, lightweight, labor-saving, and quick opening and closing. Expansion butterfly valves not only have the function of compensating for thermal expansion and contraction caused by pipeline temperature difference contraction, but also provide convenience for valve installation and replacement during maintenance. The se1
Product Introduction: Manual ball valve is a relatively new type of ball valve, which has some unique advantages of its own structure, such as no friction on the switch, less wear on the seal, and small opening and closing torque. This can reduce the specifications of the equipped actuator. Equipped with a multi turn electric actuator, it can achie1
Product Name: Electric Metal Sealed Fixed Ball Valve Product model: Q947H/Q947Y Ball valves are used in the extraction, refining, processing, and pipeline transportation systems of oil, natural gas, coal, and ores; In the production of chemical products, pharmaceuticals, and food; Ball valves are used in power production systems for hydropower, the1
Sealing characteristics of valve seats: The valve seats of floating ball valves are mostly made of polymer materials such as polytetrafluoroethylene and para polystyrene, which have good sealing performance, but the materials are relatively soft. Due to the softness of the material but the need to achieve a certain sealing pressure ratio, it is nec1
