SV-9M series Sanitary Tri Clamp Pressure Relief Valve is used to protect pipe lines, pumps from over pressured, it prevents operation danger and equipment breakdown. With stainless steel design, the valve is the best choice for protecting equipment in diary, food, beverage, pharmaceutical and fine chemical industries.


● The valve is normally closed.
● Pressure is set by calibrating the spring with pressure nut.
● When the pressure in the pipe exceeds to the specified pressure, the valve open automatically to make the liquid flow in order to reduce pressure.
● The valve can be with handle to realize partial open. The CIP liquid can flow through the valve when the handle remains open on the spot.
