Cartridge Relief Valve 3 Tricks for Optimization
The Cartridge Relief Valve 3 Tricks for Optimization is a hydraulic direct-acting cartridge relief valve that has been re-engineered to improve low-pressure stability. The redesign replaces the original poppet spool with an integral ball-type spool and adds an annular gasket between the ball and the spring. A ring seal substitutes the previous wire seal, enhancing sealing performance around the steel ball. Built-in pressure-regulating knob and spring balance provide automatic overflow control.
Typical valves of this class are fabricated from carbon steel bodies with a standard steel ball component, offering a pressure rating up to 250 bar. The usual flow coefficient (Cv) ranges from 10 to 30, suitable for hydraulic power units in precision machine tools. Standard connection size is 1/2 in. NPT, and the operating temperature range commonly spans -20°C to 120°C. Dimensions are typically around 100 mm × 80 mm × 80 mm and the unit weighs about 2 kg.
The valve is used in hydraulic power units for high-precision machining centres, where stable overflow control at low pressure is critical. Aak Industry Co., Ltd can supply small batches for prototype testing, but buyers should confirm the exact minimum order quantity and lead time. The supplier mentions harbour trust tier but does not list specific certifications, so verification of material grades and test reports is advisable.

Sourcing Cartridge Relief Valve 3 Tricks for Optimization from Aak Industry Co., Ltd - China Import Guide
Before confirming a purchase, request the detailed engineering drawing and a material test certificate to verify the carbon-steel grade and pressure rating. Ask for photographs of the ball-type spool, annular gasket and ring seal to ensure the three optimisation steps have been applied. Because the supplier’s response rate is currently zero, consider using a formal inquiry and, if possible, a local representative to assess communication reliability.
Aak Industry Co., Ltd states that shipments can be organised from the Ningbo port under FOB terms, with CIF possible upon request. Verify the expected lead time, freight charges and required export documentation such as the commercial invoice and packing list. Discuss payment arrangements, typically a telegraphic transfer or a letter of credit, and confirm any advance payment requirements before production begins.
Arrange an independent inspection to confirm that the valve meets the specified pressure rating and that the ring seal and annular gasket are correctly installed. Request a functional test report that records the valve’s opening pressure and overflow stability at low pressure. Ensure the inspection agency provides a certificate of conformity together with the supplier’s material test report.
