IMPORTANT PRECAUTIONS

Directional valves with motor spools (service ports connectedto tank in neutral) should always be used in conjunction with these valves. All ports are B.S.P. parallel, and appropriate fittings must be used. Tapered fittings are not acceptable. Port C should always be connected directly to the actuator port or by a solid line of adequate strength, to minimise the possibility of line rupture and consequent system failure. Failure to correctly install or set these valves may result in damage to property, personal injury or death.

NOTES

 VALVES ARE NOT PRESET, AND MUST BE ADJUSTED TO SUIT EACH APPLICATION PRIOR TO USE, USING APPROPRIATE TESTING EQUIPMENT.ALL DETAILS ARE APPROXIMATE, AND SUBJECT TO CHANGE WITHOUT NOTICE.
