Automatic Control Valves – Heavy Duty Pilot Operated Valves

The Allied Pumps’ WaterMark™ approved Automatic Control Valves comprise of heavy duty cast construction with direct acting diaphragm configuration eliminating the need for shafts, seals or bearings with the water passage.

The direct controllable opening and closing speed totally eliminates the hydraulic shock and water hammer associated with direct acting conventional valves.

Automatic control valves are used in commercial and industrial applications to control water flow or pressure. We offer automatic control valves that are used to ensure uninterrupted water service during emergencies, maintain a constant liquid level in tanks, automatically reduce a higher upstream water pressure to a constant downstream pressure, and for other purposes.
