Corrosion resistant multi-channel valve company

Multi-channel valvemanufacturer

Multi channel diaphragm valveThe structural form of the valve is very different from that of a general valve, as it relies on soft rubber molds or plastic films to control fluid movement. Specially designed for hygiene and aseptic processes such as pharmaceuticals and purified water, this valve is highly suitable for fluid control and switching tasks.

1Product Features

1. Suitable for corrosive, viscous, and slurry media.

2. It cannot be used in high-pressure situations.

3. Can be used for media containing hard suspended solids; Due to the fact that the medium only comes into contact with the valve body and diaphragm, there is no need for a stuffing box, and there is no problem of stuffing box leakage, which may cause corrosion to the valve stem.

IIworking principle

　　Multi channel diaphragm valveReplace the valve core component with a corrosion-resistant lined valve body and a corrosion-resistant diaphragm, and use the movement of the diaphragm to regulate it. The valve body material of the diaphragm valve is made of cast iron, cast steel, or cast stainless steel, and lined with various corrosion-resistant or wear-resistant materials, diaphragm material rubber, and polytetrafluoroethylene. The lining diaphragm has strong corrosion resistance and is suitable for regulating highly corrosive media such as strong acids and alkalis.

Diaphragm valves have a simple structure, low fluid resistance, and greater flow capacity compared to other types of valves of the same specifications; No leakage, can be used for regulating high viscosity and suspended particle media. The diaphragm isolates the medium from the upper chamber of the valve stem, so there is no packing medium and it will not leak out. However, due to the limitations of diaphragm and lining materials, the pressure resistance and temperature resistance are poor, and it is generally only suitable for nominal pressures of 1.6 MPa and below 150 ℃.

　　Multi channel diaphragm valveThe flow characteristics are close to fast opening characteristics, approximately linear before 60% of the stroke, and there is little change in flow after 60%. Pneumatic diaphragm valves can also be equipped with feedback signals, limiters, and locators to meet the needs of self-control, program control, or flow regulation. The feedback signal of the pneumatic diaphragm valve adopts non-contact sensing technology. This product uses a thin film propulsion cylinder instead of a piston cylinder, eliminating the disadvantage of the piston ring being easily damaged, causing leakage and preventing the valve from opening and closing. When the gas source malfunctions, the handwheel can still be operated to open and close the valve.
