Denison Hydraulics Pressure Relief Valves
Denison Hydraulics pressure relief valves offer high performance, sensitive control together with a range of mounting configurations and control options…
Denison Hydraulics pressure relief valves for in-line mounting series R4V have a similar design to the subplate mounted R4V series. For single functions – where no manifold blocks are used – the valves can be directly placed in the pipework.
The R4V valves are available with 2 ports (L-body, models R4V06 and R4V10) for in-line relief function or with 3 ports (T-body, models R4V03 and R4V06) for relief functions in the bypass.
Features include: Pilot operated with manual adjustment, 2 interfaces: L-body (R4V06-G¾”, R4V10-G1¼”) and T-body (R4V03-G½”, R4V06-G1″), 3 pressure stages, 3 adjustment modes, hand knob, acorn nut with lead seal, cylinder lock, optional vent function.
Denison R4V*P2 series proportional pressure relief valves are based on the mechanically adjusted Series R4V. The additional proportional unit between the mechanical pilot valve and the main stage allows continuous pressure adjustment.
The optimum performance can be achieved in combination with the digital amplifier module PCD00A-400.
Features include: Pilot operated with manual adjustment, continuous adjustment by proportional solenoid, 3 pressure ranges, mechanical maximum pressure adjustment.
Denison Series R5V pilot operated pressure relief valves have a similar design to the subplate mounted R4V series. The SAE flanges allow to mount the valves directly on the outlet flanges of pumps or inlet flanges of actuators to achieve a very compact design.
Valves with SAE flanges can also be bolted together to combine functions without the need of a manifold block. Other features of the R5V series include:
- Pilot operated with manual adjustment;
- R5V with 2-port body: 3 sizes (SAE 3/4″, 1″, 1-1/4″), SAE 61 flange;
- R5V with 3-port body: 4 sizes (SAE 3/4″, 1″, 1-1/4″, 1-1/2″), SAE 61 and SAE 62 flange;
- 3 pressure stages.
- 3 adjustment modes: Hand knob, Acorn nut with lead seal, Key lock with optional vent function.
Denison R5V series pressure relief valves are available in nominal sizes: R5V06, R5V08, R5V10 and R5V12.
