Designed for demanding mobile and industrial fluid power applications, the CRV-22A series features a balanced piston main stage with an external drain and integral 8A control cavity, delivering precise and efficient pressure regulation in hydraulic circuits requiring advanced pilot-operated relief functionality. \u003c\/p\u003e\n\u003cp class=\"gf_gs-text-heading-2\"\u003eFeaturing a T-22A cavity design, operating pressures up to 350 bar (5,076 psi), and flow capacities up to 120 L\/min, these hydraulic relief valves are ideal for hydraulic manifolds, mobile equipment, industrial machinery, hydraulic power units, and cross-port relief circuits requiring pilot-operated unloading and remote venting control. The HAWE CRV-22A series is available with multiple minimum control pressure spring options for both low-pressure and higher pressure-drop applications and is compatible with T-8A cavity pilot controls including CPRB-8A-2D and CRPA-8A-2D-74 configurations. Designed with fast typical response times of approximately 10 ms, low leakage characteristics, and balanced piston construction for stable operation, the CRV-22A valve series helps improve hydraulic efficiency, pressure stability, and overall system reliability in demanding operating environments. The valve is also designed to accept maximum pressure at port 2 for cross-port relief applications, while maintaining reliable pilot-operated performance when properly configured. \u003c\/p\u003e\n\u003cp class=\"gf_gs-text-heading-2\"\u003e\u003cstrong\u003eWarning: Improper valve selection, pressure adjustment, installation, or hydraulic system integration may result in uncontrolled pressure conditions, hydraulic system failure, equipment damage, serious injury, or death. When used in cross-port relief applications, spool leakage should be considered during system design, and back pressure at port 4 increases pilot pressure at port 1 on a 1:1 ratio plus bias spring pressure. Pressure at port 4 must not exceed 350 bar. Always verify system compatibility, follow manufacturer installation torque specifications, ensure proper vent, drain, and pressure settings, and adhere to all hydraulic safety procedures before operation.\u003c\/strong\u003e\u003c\/p\u003e","brand":"Hawe Hydraulik","offers":[{"title":"Default Title","offer_id":52506940965157,"sku":"5003 8120-00","price":127.18,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0252\/8375\/6086\/files\/CRV-22A_6c33feda-72f1-4d9c-83e7-067a8eab1fdd.png?v=1780593382","url":"https:\/\/www.onehydraulics.com\/products\/crv-22a-40-w-l-hawe-hydraulik-relief-valve-ventable-pilot-operated-balanced-piston-external-drain-4-ports-t-22a-cavity-31-7gpm-152-4567psi-1015psi-standard-hex-socket-screw-similar-to-rved-lwn","provider":"OneHydraulics","version":"1.0","type":"link"}
