Original Manufacturers Part. Fits Heliocol and Sunstar Panels. Allows water to drain from panels to prevent freezing.

HOT WATER SUPPLY Our vacuum relief valve is designed specifically to protect the hot water supply system where over-pressure conditions are likely to occur as a result of thermal expansion. DOMESTIC AND COMMERCIAL APPLICATIONS Can be used for both domestic household and commercial job site applications. COMPLETELY AUTOMATIC The VR20 Vacuum Relief Valve reseals after pressure relief. INSTALLATION The valve may be installed directly on the tank or in a tee and is appropriate for either side hot or cold of the water heater.

Adjustable Vacuum Release Valve for Vacuum Trucks and Vacuum Trailers. 1-12 Diameter, 230 CFM. Durable Brass Construction. Non Code. Compatible to 366-150, PA7V108B.

For use with solar pool panels containing a 2 I.D. header 2 manifold I.D. 2.375 manifold O.D... Fits rubber coupling hoses with a 2.375 2-38 I.D. See ASIN B07S39RH46. Internal components feature a Viton o-ring for a durable and lasting seal, a glass-reinforced ball, and 5 stainless steel spring.. A vacuum relief valve is typically installed at the highest point of a solar pool heating system. This valve allows air to into the system whenever the pump shuts off to eliminate the vacuum created by water draining back to the pool.. Gravity drainage is a necessary component of any solar pool heating system to keep air from stagnating in the panels piping, as well as minimize freeze damage from water expanding in the solar collectors..

Relief pressure adjustable from 0 to 30 Hg. 38 male NPT threaded inlet connection. Brass construction and stainless steel spring for corrosion resistance. Proportional relief valve for variable opening rate. Preset to 20 psi with 5 cfm maximum flow rate.

DESIGNED TO protect hot water supply systems and pressure vessels against negative pressure. APPLICATION suited for many domestic and commercial systems. PREVENTS internal vacuum conditions that could result in burned out heaters andor collapsed storage tanks - especially copper. INSTALLATION installed on the coldwater supply line, the VR-801 closes tightly under pressure and opens at a 1-inch mercury vacuum. Atmosphere admitted to the system breaks the vacuum, preventing collapse of the storage tank. It is recommended that the VR-801 be installed in am upright position.
