This valve can be integrated into the NF30, NF100 and NF300 series pump heads. The models NF30, NF100 and NF300 liquid pumps can be fitted with integral adjustable-pressure relief valves. They are used mainly for protecting downstream systems from overpressure damage due to system blockage, or for discharge pressure regulation. In addition to the valves, KNF offers a unique liquid pulsation dampener. The UFPD liquid pulsation damper was developed because of increased interest in low pulsation performance. The inherent pressure waves created by an oscillating diaphragm pump are reduced. It also aids in the reduction of vibration in system hoses and pipes. With the correct selection of damper, a pressure fluctuation of less than 3 psi (200 mbar) can be achieved. They are available built to NSF standards.
