Self-Locking Discharge Valves

Since the 1960’s, Darley has been manufacturing the best discharge ball valve on the market. Designed with a self-locking feature, the valve allows for stable hands free operation. The valve also features a stainless steel ball and a bronze seat. Are you tired of replacing your ball valves year after year? Our ball valve can be rebuilt in minutes resulting cost savings and continued performance. Another added benefit of the Darley ball valve is the adjustable handle, which can be clocked in 45 degree increments to allow for varying applications.

Discharge Check Valve

Darley’s discharge check valve is designed to improve attack time. By isolating the discharge plumbing from the pump cavity, the pump can be primed with open discharge gates. When the pump achieves prime, the discharged water forces the check valve to an opened position. The simplicity of the design allows for easy maintenance and trouble free operation.

Vacuum Cast Impeller

Darley twisted vane impellers are vacuum cast to eliminate porosity, broached to fit a 10-splined shaft rather than a single key and precision balanced for smooth operation and optimal efficiency all resulting in reduced cost of ownership and the most efficient and durable fire pump on the market.
