CHECK VALVE GW 2" STRAIGHT SS316 HYDRAULIC STAINLESS STEEL


PLN100.41 (PLN123.50 brutto)

2" stainless steel straight check valve with BSPP (G) female thread, designed for use in large-scale hydraulic lines, industrial systems, and process systems with maximum flow rates. Constructed from high-grade CF8M (SS316) austenitic acid-resistant 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 poppet seals (metal-to-metal sealing). This solution ensures exceptional component longevity, 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) across a wide temperature range from -20°C to +180°C.

Seal-less design – a guarantee of longevity

The main advantage of this 2" 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 at maximum flow rates. The only static seal on the body itself is made of reliable Teflon (PTFE), which minimizes the need for any maintenance and ensures trouble-free operation for years.

Maximum 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 on main supply and transmission lines with large nominal diameters. 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 main transmission 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 2" GW connections on both ends allow for secure installation in existing large-diameter pipelines.
