Parker RVP20CF Check valve
It is a high-performance hydraulic check valve designed for industrial hydraulic systems and mobile equipment to prevent fluid reverse flow and ensure system pressure stability. This valve belongs to Parker's RVP series, which is known for its compact structure, high sealing and durability, and is suitable for harsh hydraulic application environments.
Key features
(1) Technical parameters
Type: In-line check valve, allowing free flow in one direction and blocking in the reverse direction.
Pressure range:
Maximum working pressure: 350 bar (some models can reach 420 bar).
Opening pressure: 0.35 bar (standard), optional low opening pressure (0.1 bar).
Flow capacity:
Cv value: 1.5 (refer to the curve for specific flow).
Recommended flow rate: ≤6 m/s (avoid turbulence and noise).
Interface size:
RVP20 corresponds to ISO 20 (i.e. 3/4" NPT or G3/4" thread).
Material:
Valve body: Carbon steel with nickel plating (standard) or stainless steel (316L, corrosion resistant).
Valve core: Hardened steel (wear resistant) or ceramic (long life).
Seal: NBR (standard), FKM (high temperature/chemical compatibility) or polyurethane (impact resistant).
(2) Performance advantages
✅ Low leakage: Precision ground valve seat, excellent reverse sealing performance (leakage <1 drop/minute).
✅ Fast response: Spring preload design ensures fast closing (response time <10ms).
✅ Pollution resistance: Can tolerate ISO 4406 20/18 pollution level (no fine filtration required).
✅ Modular design: Can be integrated into multi-way valve block or installed separately.
