High Pressure Relief Valve - UFHP4 Series
The APV UFHP4 High-Pressure Relief Valve, part of the UF Series, is designed to protect pumps and process equipment from damaging pressure spikes, extending the capabilities of the UF4 line with relief pressures exceeding 10 bar compared to UF4's 0-10 bar range. Featuring an integrated Control Unit for monitoring relief events and valve actuation during CIP cleaning.
