Hydraulic Pressure Control Valves – Relief, Reducing, Sequence & Proportional
John Henry Foster offers a full range of pressure control valves for efficient and reliable fluid regulation across industrial and mobile hydraulic systems. Our selection includes relief valves, reducing valves, sequence and unloading valves, and proportional valves, available in multiple mounting configurations to suit your system needs.

From modular manifolds to direct-mount installations, JHF offers high-performance pressure control valves from trusted brands like Bosch Rexroth and Sun Hydraulics—engineered for flexibility, durability, and precision.

Valve Functions

  • Relief valves: Protect systems from overpressure

  • Reducing valves: Maintain consistent downstream pressure

  • Sequence & unloading valves: Direct flow in priority or staged operations

  • Proportional valves: Enable variable control based on system demand

Mounting Options

  • Line mounted – easy installation directly in the hydraulic circuit

  • Subplate mounted – compact, interchangeable design for valve manifolds

  • D03–D10 modular stack valves – ISO/NFPA compliant for space-saving assemblies

  • Direct flange mounted – rugged integration for high-flow or custom blocks
