Shand & Jurs - Model 94050 - Polyvinyl Chloride Conservation Vent (Pressure/Vacuum)
The Shand & Jurs PVC Conservation Vents are designed for highly corrosive service where toxic liquids are stored. They are an excellent alternative to coated metal construction, where frequent corrosion due to the presence of pinholes is a problem. PVC valves are intended to provide pressure and/or vacuum relief on atmospheric storage tanks requiring normal venting.
This valve functions in the same manner as standard metal construction pressure/vacuum valves, preventing excessive product evaporation losses due to normal tank breathing. Controlling emissions of toxic and corrosive vapors to the atmosphere is a beneficial consideration.
Available in various venting configurations: pressure only, pressure/ vacuum or vacuum only,with choice of end-of-line or pipeaway styles.
Diaphragms are cushion seated and are constructed of FEP Teflon for reliability and extended service life. Valve design utilizes both peripherally and stem guided pallets for dependable operation.
