STANDARD INLETS The inlet covers come with G(BSP) ports in either top or side positions. They can be fitted with or without a relief valve. They are supplied in open centre configuration as standard but can be specified for use in closed centre systems. If a solenoid spool section is used in the assembly an ‘E’ type inlet is used which contains additional drillings for the pilot connections. We can also include an auxiliary port for fitment of a pressure gauge. Side port Relief Valve Adjustable. Pilot Operated or Direct Acting. Material Cast Iron Weight 0.75kg
