The Five Function Valve is packed with features that increase safety, enhance performance and generally improves the convenience of operation. The functions are selected by setting two dual position selector knobs. The label on the back panel of the valve identifies each function with selector knob positions. The Five Function Valve is compatible with most Pulsatron, and CHEM-TECH Series pumps. Connected to the existing discharge valve the Five Function Valve is capable of handling a large output flow as well as viscous liquids. A return port located on the side body provides flow of chemical back to the solution tank when in the air bleed or drain discharge mode.

• Pressure Relief Back Pressure - Maintains output reproducibility and allows metering into atmospheric discharge.
• Anti-Siphon - Prevents siphoning through the pump when point of injection is lower than the pump or into the suction line of another pump. Rated at total vacuum.
• Air Bleed - Used during priming to manually remove air from the pump head.
• Discharge Drain - Depressurize pump discharge
