Sanitary solenoid valves with clamp connections - Overview, Technical Parameters & Working Principle

Sanitary solenoid valves with clamp connections refer to valve fittings used in places with high hygiene level requirements such as pharmaceutical and food industries. The sanitary solenoid valve with clamp connections adopts a non-heating coil with small power, undergoes internal and external polishing and sterilization treatment, and is a quick assembly-disassembly valve, making valve opening and maintenance fast and easy. It has strong oxidation resistance and corrosion resistance. The valve body material used for the sanitary solenoid valve with clamp connections is 304 stainless steel and 316 stainless steel, and its sealing material mainly adopts silicone rubber and polytetrafluoroethylene (PTFE), which is sturdy and durable, suitable for working in harsh environments.

Working Principle of Sanitary Solenoid Valve with Clamp Connections

The sanitary solenoid valve with clamp connections adopts a combined principle of direct-acting and pilot-operated. When there is no pressure difference between the inlet and outlet, after energization, the electromagnetic force directly lifts the pilot valve and the main valve closing part upward in sequence, and the valve opens. When the pneumatic pressure difference is reached between the inlet and outlet, after energization, the electromagnetic force acts on the pilot valve, the pressure in the lower chamber of the main valve rises, and the pressure in the upper chamber drops, thereby pushing the main valve upward by using the pressure difference; when de-energized, the pilot valve pushes the closing part downward by using spring force or medium pressure to close the valve.

Normally Closed Type: Opens when energized, closes when de-energized; Normally Open Type: Closes when energized, opens when de-energized
