Fisher™ SR5 Sanitary Pressure Regulator
The Emerson Type SR5 sanitary regulator is a compact, large capacity, direct-operated pressure reducing regulator. It is designed for use in applications where a sanitary design is essential, such as pharmaceutical, biotech or food and beverage industries. The unit is available in 1/2 through 3 in. / DN 15 through 80 sizes with end connections that will match up to Tri-Clamp® sanitary fittings. The Type SR5 is suitable for use in steam, liquid or gas service.
The Type SR5 is a direct operated regulator. Pressure in the controlled system (regulator outlet pressure) registers beneath the diaphragm of the regulator and opposes the force provided by the predetermined spring compression. When regulator spring force exceeds diaphragm force exerted by the outlet pressure, the spring will keep the valve plug open to permit additional flow to the downstream system. As downstream demand decreases the outlet pressure will increase, this increase registers on the diaphragm and the valve plug moves closer to the orifice to decrease the flow rate.
