DESCRIPTION		FUNCTION		APPLICATION

Pilot operated spool valve in flange type NG10 with 4 connections. Pilot valve as direct operated spool valve with a 5 annular chamber body design. Spool made from hardened steel. Valve body made from high grade hydraulic cast iron. EE in accordance with european standards EN 50014, EN 50018 d flameproof enclosure roup II C (gas group II A, II B) for all applications except mining one 1 (and 2) explosive mixtures present intermittently EC t pe e a ination certi icate Execution T4: PTB 98 ATE 1009 Execution T6: PTB 98 ATE 1008		By operating the pilot valve pressure will be applied to one end of the main spool and move it into activated position as indicated on lable. 4/2-way impuls valve 4/3-way spring centered 4/2-way spring reset (see data sheets of the corresponding pilot valves) Pilot pressure supply and drain either internal are as an option external through a ported sandwich plate between main and pilot valve.		Solenoid operated spool valves are mainly used to control the direction of movement and retain hydraulic cylinders and motors. The direction of flow through the valve is determined by the spool symbol. Pilot operated valves are used where high flows have to by controlled. These valves are suitable for hazardeous areas in off-shore and shipbuilding applications as well as in chemical, oil and gas industry.
