Enerpac V-152 - Manual (Page 2)

OPERATION
System pressure is applied to the piston C. The hydraulic
pressure on piston C will act against the compression
spring B and lift the cone off of the seat, allowing oil to
flow through orifice A to tank. The oil passes through the
orifice until the oil pressure is equal to the compressive
force of the spring. At that time, the cone will move upon
the seat. This process is then repeated over and over again.
Just enough oil from the system is allowed to pass through
the orifice, automatically maintaining the system pressure
as set by the valve.
• To increase setting, turn the handle clockwise.
• The handle may be removed to prevent tampering with the
valve’s settings
• The V152 is not a load-holding valve.
