The latest addition to Sterling Hydraulics’ (UK) range of pressure relief valves is the A04B2*CE. Like the A04J2 valve, the new valve is fully compliant with the pressure equipment directive (PED 976/23/EC). The PED relates specifically to equipment which has a high stored energy level. This includes, for example, nitrogen-charged accumulators that retain pressurised oil for release on demand, to operate a hydraulic service, such as a vehicle braking system. The valve’s poppet-style construction ensures low leakage whilst the hardened working parts provide for maximum durability. The new uni-directional A04B2 relief valve is rated to 420 bar with a flow capability of 100l/min. Like the A04J2, it is a direct-acting valve and has the same rapid response time. Both valves fit into an industry standard 10-2 common cavity and have a tamper-proof setting feature as standard.
