Spirax-Sarco BRV2S Pressure Regulators & Vacuum Breaker

Adjustable Pressure Regulators for Steam and Compressed Air with Stainless Steel Bellow The Spirax-Sarco BRV2S adjustable pressure regulator for steam & compressed air pressure reducing applications, and low to medium-sized capacity installations. Iron body construction with a high quality stainless steel bellow assembly for years of durable operation. Select from 1/2, 3/4 and 1 pipe thread connections. Select from three adjustable pressure control ranges: 2 to 25, 20 to 60 and 50 to 125 psi.

Note: where the pressures overlap, use the lowest pressure range that can provide the downstream pressure required. Maximum Operating Temperature: 410 F. Great for steam pressure and inert gases (such as compressed air) up to 275 psi upstream, and 115 psi downstream.

Spirax Sarco VB14 & VB21 Vacuum Breakers Spirax Sarco Vacuum Breakers are available in brass body construction (Model VB14) or stainless steel body construction (Model VB 21). Both mod-els have stainless steel internal valve components. These premium quality vacuum breakers are used on the steam inlet to air coils, heat exchangers, sparge systems, jacketed kettles, boiler feed water tanks, chilled water lines, liquid process lines and other steam or liquid systems where vacuum for-mation inhibit the needed drainage from the sys-tem or prevent proper system operation. The vac-uum breaker relieves the vacuum condition that is often generated in the equipment.
