H1 - HM1 Series Pressure/Vacuum Relief Valves are used to maintain positive pressure in hydraulic reservoirs. The compact size, reusable bronze filter and high flow characteristics make this valve a popular choice. The HM1 version offers the same features and characteristics as the H1 Series with the option of a manual over ride function. This feature allows the operator to relieve the reservoir pressure before opening the tank for refilling, inspection or servicing. The H1 - HM1 Series are available in a wide range of pressure relief settings from 5 psi to 50 psi (in 5 psi increments) and a vacuum relief setting of 0.3 psi.
