PRE-CON VALVES are suction inlet valves designed to operate as automatic flow control valves. This eliminates the need for manual adjustments in relation to water flow.
The PRE-CON PC 30 comes standard with a field-adjustable relief valve, large air purge valve at a stress-relieving 30° angle for Storz or large NST hose. The PC 30 only opens as far as necessary for the discharge flow requirements. As discharge lines or nozzles are opened or closed, the PC 30 continually adjusts for changes in water flow. The straight-through design enhances flow and eliminates cumbersome 90° elbows that can interfere with pump controls.
The PRE-CON PC 3 is the choice of fire departments involved in drafting operations because of the automatic check valve action. Suction hose prime water is retained when flow is stopped or switched to booster tank operations. The compact design keeps pipe extension to a minimum and no remote valve controls are needed. The PC 3 is suited for both front and rear suction inlets.
Note: Pre-con automatic inlet values are Patented. Pre-con valves are suction inlet valves designed to operate as automatic flow control valves. This eliminated the need for manual adjustments in relation to water flow.
