How much does a double acting plastic ball valve cost

Electric plastic ball valveSuitable for intercepting flow in the transportation process of corrosive media, with different material temperatures ranging from -14 ℃ to 100 ℃ and -40 ℃ to 140 ℃. All parts are assembled using RPP or PVDF injection molded parts, and the plastic ball valve has excellent corrosion resistance. The sealing ring adopts F4. It has excellent corrosion resistance and extends its service life. Flexible rotation and convenient use. Plastic ball valve integral ball valve has fewer leakage points, high strength, and easy installation and removal of connected ball valves. Classification of plastic ball valves: flanged plastic ball valve, threaded plastic ball valve, socket plastic ball valve, double threaded plastic ball valve

Electric plastic ball valveIt is mainly used to cut off or connect media in pipelines, and can also be used for fluid regulation and control. Compared with other valves, it has the following advantages. 1. Low fluid resistance, ball valves have the lowest fluid resistance among all valve types, even for reduced diameter ball valves, their fluid resistance is quite small. UPVC ball valve is a new material ball valve product developed in recent years according to the requirements of various corrosive pipeline fluids. Product advantages: The valve body is lightweight, corrosion-resistant, compact and beautiful in appearance, easy to install, corrosion-resistant, widely applicable, made of hygienic and non-toxic materials, wear-resistant, easy to disassemble, and easy to maintain. In addition to UPVC plastic material, plastic ball valves also include RPP, PVDF, PPH, CPVC, etc.

Plastic ball valves have the characteristics of simple structure, small volume, light weight, low material consumption, small installation size, fast opening and closing, 90 ° reciprocating rotation, and small driving torque. They are used to cut off, connect, and regulate media in pipelines, and have good fluid control characteristics and sealing performance.

Plastic ball valves can transport mud and accumulate the least amount of liquid at the pipe mouth. Under low pressure, good sealing can be achieved. Good regulation performance. The streamlined design of plastic ball valves reduces fluid resistance losses, making them an energy-saving product.

The valve stem is a through stem structure that has undergone quenching and tempering treatment, and has good comprehensive mechanical properties, corrosion resistance, and abrasion resistance. When the ball valve is opened and closed, the valve stem only rotates and does not move up or down. The packing of the valve stem is not easily damaged and the seal is reliable. Fixed with the butterfly plate cone pin, the extended end is designed to prevent the valve stem from bursting out in case of accidental breakage at the connection between the valve stem and the butterfly plate. The connection methods include flange connection, clamp connection, butt welding connection, and lug clamp connection. The driving forms include manual, worm gear transmission, electric, pneumatic, hydraulic, electro-hydraulic linkage and other actuating mechanisms, which can achieve remote control and automated operation. The disadvantages of ball valves are as follows:

1. The pressure and working temperature range are small.

2. Poor sealing performance.
