CHECK VALVE GW 1 1/4" STRAIGHT SS316 HYDRAULIC STAINLESS STEEL


PLN76.02 (PLN93.50 brutto)

5/4" (1 1/4") stainless steel straight check valve with BSPP (G) female thread, designed for use in medium- and large-capacity hydraulic lines, industrial systems, and process systems. Constructed from high-grade CF8M (SS316) acid-resistant austenitic stainless steel, it guarantees complete resistance to corrosion, extreme temperatures, and long-term exposure to aggressive chemical media.

The device operates in a unidirectional manner with mechanical spring return and features a unique design without additional flexible seat seals (metal-to-metal sealing). This solution ensures exceptional longevity of the component, eliminating the problem of aging and damage to plastic seals. The valve is designed for operation at high working pressures up to 63 bar (PN63) over a wide temperature range from -20°C to +180°C.

Seal-less design – a guarantee of longevity

The main advantage of this 5/4" check valve is the complete elimination of soft elastomeric seals on the pressure disc. The use of a precisely fitted metal flap ensures that the valve exhibits exceptional resistance to mechanical wear, erosion caused by high-velocity fluid flow, and chemical degradation under high liquid flow rates. The only static seal in the body itself is made of reliable Teflon (PTFE), which minimizes the need for any maintenance and ensures trouble-free operation for years.

High flow capacity and high operating pressure

Thanks to its CF8M (SS316) steel casting and excellent PN63-class strength parameters, the valve can safely shut off backflow in distribution and supply lines. It is fully compatible with media such as water (including process water, hard water, and demineralized water), neutral gases and liquids, alcohols, industrial oils, glycol, and organic solvents. This design is widely used in industrial, hydraulic, food processing, and central heating systems.

Reliable spring-operated action on distribution lines

The valve is equipped with an internal spring mechanism that automatically and immediately closes the circuit when flow ceases or reverses direction. This protects the system against water hammer and effectively safeguards pumps, meters, and other sensitive components from backflow damage. Standard 5/4" GW connections on both ends allow for reliable installation in existing piping systems.
