Series PRH-U Ultra-Pure Pressure Regulators

The Series PRH-U regulators provide not only higher set pressures and flow capacities with each model, but these are achieved with less pressure loss than with similar size competitive regulators. The one-piece body construction and dual U-cup shaft seals help to eliminate internal leakage that could cause the set pressure to creep beyond a safe limit. This unique design, in conjunction with a balanced pressure shaft, assures smooth performance and stable control. Additional fittings, sizes, and materials are available, call us for a quote.
