The operator can quickly reverse fluid direction by hand, making this valve well suited for load holding applications with both single-acting and double-acting cylinders. The integral relief valve is factory set at 11,500 psi. Oil port connections are 3\/8 inches NPTF. This valve is typically installed by hydraulic technicians and maintenance professionals working with industrial or high-pressure hydraulic circuits.\u003c\/p\u003e\n\u003cp\u003eThe v-66 is appropriate for industrial hydraulic applications where load holding and precise directional fluid control are required. It is compatible with single-acting and double-acting hydraulic cylinders. A corrosion-resistant variant, the v-66NV, incorporates Viton seals and a nickel-plated finish for use in environments where exposure to moisture or corrosive media is a concern. The v-66F variant offers very fine metering capability for precise flow control, though it is not rated for load holding applications.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eBuilt-in relief valve set at 11,500 psi for integrated overpressure protection\u003c\/li\u003e\n  \u003cli\u003eManual operation allows quick reversal of fluid direction without additional tooling\u003c\/li\u003e\n  \u003cli\u003eSupports load holding with single-acting and double-acting cylinders\u003c\/li\u003e\n  \u003cli\u003e3\/8 inches NPTF oil port connections for standard hydraulic plumbing\u003c\/li\u003e\n  \u003cli\u003ev-66NV variant includes Viton seals and nickel-plating for corrosion resistance\u003c\/li\u003e\n  \u003cli\u003ev-66F variant provides fine metering for precise flow control applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with single-acting and double-acting hydraulic cylinders in industrial hydraulic circuits.

Depressurize the hydraulic system completely and verify zero stored pressure before connecting or disconnecting any fittings. Use thread sealant appropriate for NPTF connections and torque fittings according to the system plumber's standard practice for the port size. Do not use the v-66F model in load holding applications, as it is not rated for that service.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRelief Valve Setting\u003c\/strong\u003e: 11,500 psi (790 Bar)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOil Port Connection\u003c\/strong\u003e: 3\/8 inches NPTF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOperation Type\u003c\/strong\u003e: Manual\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eValve Function\u003c\/strong\u003e: Check valve with built-in relief valve\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCompatible Cylinder Types\u003c\/strong\u003e: Single-acting and double-acting\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: ENERPAC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: v-66\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ENERPAC","offers":[{"title":"Default Title","offer_id":51524538794290,"sku":"V-66","price":700.04,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/77cedf69af57f50a3ed901bc6f093ed9.jpg?v=1785451238","url":"https:\/\/voomisupply.com\/products\/enerpac-v-66-check-valve-with-built-in-relief-valve","provider":"Voomi Supply","version":"1.0","type":"link"}
