B-Series Direct-Operated Pressure Regulating Valve

Brand: Watson McDaniel

The B-Series direct-operated pressure regulators with balanced valve trim are used for reducing pressure in air and water systems. These regulators are commonly found in industrial plants, apartment buildings, water supply systems, schools and underground water distribution systems.

The soft-seated elastomeric Viton disc has an operating temperature up to 300° F and will produce a Class V shutoff. No external sensing line is required with this style of regulator.
Features
  • Diaphragm, disc and cup packing in Viton for 148.9° C (300º F) service
  • Balanced pressure regulator allows accurate control even when incoming pressure fluctuates
  • Valve has a Class V shut-off rating due to the "soft-seated" Viton disc
