PN16 PVC Ball Valve PVC U joint Pipe Fittings For Water System
The plastic ball valve has the characteristics of simple structure, small volume, light weight, material consumption, small installation size, rapid switch, 90° reciprocating rotation, small driving torque, etc., and is used for cutting, connecting and adjusting the medium in the pipeline. Good fluid control characteristics and closed sealing performance.
Plastic ball valves can carry mud and store the least amount of liquid at the pipe mouth. A good seal can be achieved at low pressure. The adjustment performance is good. The streamlined design of the plastic ball valve makes the fluid resistance loss small, which is an energy-saving product.
a) If the valve has only one bearing direction, it should be marked with an arrow on the outside of the valve body. The symmetrically designed valve should be suitable for two-way flow and isolation of the fluid.
b) The sealing member is driven by the valve stem to open and close the valve. It should be positioned by friction or actuator at any point or intermediate position. The fluid pressure cannot change its position.
c) According to EN736-3, the minimum through hole in the valve cavity should meet the following two points:
– any aperture in the flow of media on the valve shall not be less than 90% of the DN value of the valve;
— For valves that are structurally required to reduce the flow aperture of the media, the manufacturer shall state the actual minimum through hole.
d) The seal between the valve stem and the valve body shall comply with EN736-3.
e) In terms of valve wear resistance, the design of the valve should take into account the service life of the wear parts, or the manufacturer should indicate in the operating instructions the replacement of the entire valve.
f) The flow rate for all valve operating devices should be 3 m/s.
g) From the top of the valve, the handle or handwheel of the valve should close the valve clockwise.
