Check valve - Import export

Valves and shut-off devices are components for blocking and control of liquids or gases. The range of products includes 2-way ball valves, 3-way ball valves, hydraulic ball valves, angle seat valves, butterfly valves as well as solenoid valves, pressure switches, blocking valves, needle valves and gate valves. Coaxial valves and check valves also belong in the assortments as well as dirt strainers, safety valves and pressure limiting valves.

Robust stainless steel check valve with high flow capacity for aggressive media and high operating temperatures.

We focus on quality and consistency. Batch production are always consistent with sample. Our Quality assurance: 1. Non-destructive test (NDT): magnetic particle examination (MPE), ultrasonic examination (UE), liquid penetration examination (LPE), X ray. 2. Experienced inspector on dimensions, CMM dimension testing and other tools. 3. To maintain our reputation, we still have excellent return and claim policy even some rare defects. 4. Our prices are always competitive. 5. Spectrometers to assure the material.

Nova Swiss check valves ensure an ideal degree of leak-tightness for both gases and liquids thanks to the use of bonded metal/plastic seats. Our check valves are characterized by excellent flow rates and maximum reliability — both at low and high pressures. The replaceable seats allow simple and cost-efficient maintenance. Our high and low-pressure check valves are supplied complete with screw fittings.

Genuine DEUTZ

Non-Return Valves WITT non-return valves protect plants, pipelines and outlet points against reverse gas flow and meet all relevant standards and regulations. The product range of non-return valves includes a large choice of nominal sizes (up to DN200) and flow rates (0.35 – 106 SCFH). The sophisticated valve technology of WITT non-return valves provides small pressure drops making them also suitable for applications with smallest opening pressures. A high-quality sealing system with elastomeres prevents leakages, and dirt filters at the inlet point assure long service life of the non-return valves. Some non-return valve models can also be used as flashback arrestors. All non-return valves can be mounted in any orientation, are available with all connections, in brass and stainless steel and are suitable for almost all technical gases.
