Direct-acting relief valve - pilot capacity
SERIES 1 / CAPACITY: 1 L/min. / CAVITY: T-10A
Direct-acting, pilot relief cartridges are used to remotely control the pressure setting of other pilot-operated valves.
Because capacity is limited to pilot flow, these valves should be used with other higher flow valves.

TECHNICAL FEATURES
Main stage orifice is protected by a 150 micron stainless steel screen.
Suitable for use in load holding applications.
Back pressure on the tank port (port 2) is directly additive to the valve setting at a 1:1 ratio.
Cartridges with EPDM seals are for use in systems with phosphate ester fluids. Exposure to petroleum based fluids, greases and lubricants will damage the seals.
W and Y controls (where applicable) can be specified with or without a special setting. When no special setting is specified, the valve is adjustable throughout its full
range using the W or Y control. When a special setting is specified, this setting represents the maximum setting of the valve.
For Series 1 cartridges configured with an O control (panel mount handknob), a .75 in. (19 mm) diameter hole is required in the panel.
