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 losses than with similar size competitive regulators. 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 pressure balanced shaft, assures smooth performance and stable control. Additional fittings, sizes, and materials available, call for quote.
