Gas non-return valves / Check valves Safety devices in accordance with EN ISO 5175-2 Type: GRV 20, GRV 25, GRV 32, GRV 50 Highlights Gas non-return valve for very low cracking

Spring Check Non-Return Valves. Spring Check Non-Return Valves are simple, low cost but systems for air, gas or low pressure applications where bubble.

A flap check valve has hinged disc which is raised by the fluid passing through the pipe. Low pressure fittings have an inspection cap provided. Normal flow 

The gas non-return valves reliably prevent the reverse flow of gas. Flashback-resistant valves additionally stop flashbacks if fuel gas and compressed air mixture is used. All check valves and flashback-resistant gas non-return valves are subjected to a 100% quality test. The leak-tightness and the function of the gas non-return valve are tested.

Non-return valves are key safety devices in gas systems, plants and pipelines. They prevent the formation of dangerous gas mixtures and other 

Relatively low flow resistance. The butterfly non-return valve is a typical non-return valve for water systems. In size classes greater than DN 100, the flow resistance is clearly lower than in the case of the RK model. However, if a small flow resistance is a selection criterion, the resistance is clearly higher in butterfly non-return valves

This valve is additionally named as double-disc or split disc check valve. It's factory-made in wafer-body pattern and is out there with soft or exhausting seats. It's extremely popular in low-pressure liquid and gas field services. Its light-weight compact construction makes it a preferred check valve once area and convenience are necessary.

Non-return valves are flow sensitive, and rely on the steam flow to open and close. The internal disc opens and allows the flow of steam through the valve. The disc will begin to close as forward steam flow decreases or is reversed, depending on the design.

The ALPI-NRV-LP is a low pressure non-return valve for medical gas distribution systems. It is used to prevent back feeding from one source to another and 

The non-return valve permits the medium to flow in a single direction. The reason to fit the non-return valve is to make sure that the medium is flowing inside the pipe in the correct direction. It is dependent on the condition of the pressure. Otherwise, there can be a reversal in the flow direction. The flowing medium from the non-return

The HON590 non-return valve is designed to prevent reverse flow and must be fitted (GAS ACT 1972) in the gas line where air at higher pressure is mixed with fuel gas prior to combustion and many types of industrial burners. Max. working pressure: 7

Medical Gas Check Valves Our Medical Non-Return Valves conform fully to NFPA 99-2018. The valve port is larger than the copper tube flow area to keep pressure drops low. Valves are designed for working pressures of up to 300 psig and the body is field removable for servicing without cutting or disassembling of lines.

A non-return valve lets the fluid flow in one direction. As the name implies, the primary function of a non-return valve is to keep the flow of fluid in just one direction. When fluid in the line reverses direction and begins to flow back the way it came, a check valve serves to stop or prevent the backflow by allowing flow in one direction.

This non return valve for fuel is primed. Arrow marked on body, showing fluid flow direction, prevents fuel draining back to the tank, keeps it in the line.
