工作原理

Construction

The valve consists of an AISI 316L stainless steel valve housing, spring, plug and EPDM seal. The valve housing consists of two components held together by a threaded connection. Inside there is a valve body made of polypropylene and a stainless steel spring to keep the body in open position.

The valve is typically positioned as an integrated part of the gas/CIP pipe at the top plate. It can be mounted at an angle of 45° (maximum) to the ideal vertical position. It can also be integrated with a SCANDI BREW^® tank top system.

Operating principle

The stainless steel spring forces the valve body open, enabling the full flow of gas to pass through the valve in both directions. To force the valve body into closed position, CIP fluid flows in a countercurrent direction against the spring. Due to the force of the liquid, the valve closes. A special drilled opening in the valve body ensures hygienic cleaning of all valve parts.
