*PRODUCT IMAGE IS REPRESENTATIVE PROVIDED BY THE MANUFACTURER. DO NOT MAKE BUYING DECISIONS SOLEY BASED ON THE IMAGE. PLEASE VERIFY SPECIFICATIONS MEET YOUR REQUIREMENTS.

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.

Technical Characteristics:
• Pressure Relief Setting Options (psi): 5, 10, 15, 20, 25, 30, 35, 40, 45, 50
• Vacuum Relief Setting (psi): 0.3
• Filter: 10 micron, nominal
• Filter Type: Bronze - reusable
• Thread Sizes: 3/8"", 1/2"", 3/4"", 1""
