CRG Check Valve FAQ:
1. What is the CRG Check Valve ?
The CRG Check Valve is a right‑angle, sub‑plate‑mounted hydraulic poppet‑type one‑way valve. It allows hydraulic oil to flow freely in one direction and completely blocks reverse‑direction flow. With low‑leakage cone sealing, it is mainly used for pressure‑holding, load‑locking and anti‑backflow protection in hydraulic circuits. Multiple cracking‑pressure options are available to suit different system requirements.
2. What makes the CRG Check Valve ?
The CRG Check Valve features a compact 90‑degree right‑angle flow path and ISO‑standard sub‑plate mounting. It adopts a hardened poppet‑cone sealing structure to achieve ultra‑low internal leakage and excellent pressure‑holding performance. Optimized inner‑channel design reduces forward‑flow pressure loss. Multiple cracking‑pressure selections and three available sizes (CRG‑03, CRG‑06, CRG‑10) meet different flow‑rate requirements. Its interchangeable mounting dimensions, heavy‑duty build and easy‑maintenance layout make it a reliable anti‑back‑flow component for long‑term industrial‑hydraulic operation.
3. What is the working pressure range of CRG Check Valve ?
The maximum working pressure of CRG Check Valve reaches 25 MPa (3630 PSI). Its optional cracking pressure ranges from 0.04 MPa to 5.0 MPa to satisfy various hydraulic‑circuit requirements.
4. Can CRG Check Valve replace other brands?
The CRG Check Valve follows standard‑size mounting dimensions, which can serve as a direct replacement for most mainstream CRG‑series check‑valve brands. Before replacement, please verify key parameters, including nominal size, cracking pressure, maximum working pressure and flow rate. Custom‑tailored solutions are available for special system requirements.
5. What is the Response / Switching frequency of CRG Check Valve ?
The CRG Check Valve is a poppet‑type non‑return valve that opens and closes automatically according to oil‑flow pressure. Its typical response time is around 20‑35 ms. There is no fixed rated switching frequency, as it is not designed for high‑speed cyclic switching. Frequent rapid opening‑closing operations are not recommended, which will shorten its service life. Actual performance depends on system pressure, oil viscosity and flow‑rate conditions.
6. Do you provide OEM or customized services?
Yes, we provide OEM and customized services for the CRG Check Valve. Available customization includes cracking pressure, special‑material seals, marking, and surface treatment. Please send us your technical specifications or drawings so we can offer you an accurate quotation.
