Dilution Drain Valves international polymer solutions The Dilution Drain Valve is ideal for cooling and diluting solutions while draining. The valve is designed to shut off the drain automatically if the water flow is interrupted. The DDV fits tanks with 3/8", 1/2" and 3/4" main drain ports. • With a focus on high purity applications, our PTFE and PVDF all wetted surface designs resist chemical corrosion and other harsh process environments. • Configured for easy facility hookup which only requires water pressure. Dilution Water Pressure Range: 30 psi to 90 psi. • The Fail Safe design will close the valve when dilution water is interrupted. • The Main Drain Port is protected from chips and debris with a screened Baffle Plate. • Media Operating Temperature Range Note: High dilution rates will cause slow drain rates. Used to drain a tank while diluting and cooling the discharge. • When water pressure is activated, a unique spool valve design moves forward and aspirates the tank dry. • When water pressure is deactivated, a PTFE coated isolated return spring automatically shuts off the valve. 10:1 Pressure Flow Curve Dilution Inlet Pressure (PSI) 6:1 Pressure Flow Curve Dilution Inlet Pressure (PSI) 2:1 Pressure Flow Curve Dilution Inlet Pressure (PSI) international polymer solutions inc. • manufacturer of high purity flow control products
