Maximum pressure (bar/psi) 205/3000 Peak flow (L/min/gpm) 30/8 (See performance chart)
A screw-in, cartridge-style, direct-acting, differential area, poppet-type, bi-directional relief valve, intended for use as a pressure limiting device in demanding hydraulic circuits.
• Adjustments cannot be backed out of the valve • Adjustments prohibit springs from going solid • Hardened parts for long life • Industry common cavity
