Product Description

RVCA-LBN Sun Hydraulic Relief Valves Are in Stock
 

Ventable, pilot-operated, balanced piston relief cartridges are normally closed pressure regulating valves. When the pressure at the inlet (port 1) reaches the valve setting, the valve starts to open to tank (port 2), throttling flow to regulate the pressure. They provide a vent port (port 3) that connects between the main piston and pilot stage to provide for remote control by other pilot or 2-way valves. These valves are accurate, have low pressure rise vs. flow, they are smooth and quiet, and are moderately fast.

• A remote pilot relief on port 3 (vent) will control the valve below its own setting.
• Will accept maximum pressure at port 2; suitable for use in cross port relief circuits. If used in cross port relief circuits, consider spool leakage.
• Main stage orifice is protected by a 150-micron stainless steel screen.
• Not suitable for use in load holding applications due to spool leakage.
• Back pressure on the tank port (port 2) is directly additive to the valve setting at a 1:1 ratio.
• Cartridges configured with EPDM seals are for use in systems with phosphate ester fluids. Exposure to petroleum based fluids, greases and lubricants will damage the seals.
• Incorporates the Sun floating style construction to minimize the possibility of internal parts binding due to excessive installation torque and/or cavity/cartridge machining variations.
