all of which are operated by a pressure rise in the circuit, sensed either internally or remotely. 
HC Type Pressure Control Valves These valves are hydraulically damped,
by a pressure rise in the circuit, sensed either internally or remotely. 
H Type Pressure Control Valves These valves are hydraulically damped, direct operated,
pressure control valves which can be actuated by internal or external pilot pressure.
 There are various types of valve including sequence, unloading and low pressure relief valves,
HC Type Pressure Control Valves These valves are hydraulically damped,
Oil temperatures between -15/+70°C (5 - 158°F).
 Use hydraulic fluids which satisfy the recommended viscosity and oil temperatures given above.
Due caution must be paid to maintaining control over contamination of the hydraulic
direct operated pressure control valves which can be actuated by internal
