2. Shut off the flow of water into your residence by moving the shut-off valve to the "off" position. 3. Check the meter. · If the flow readout still has a number besides "0,000," the leak is somewhere outside in the service line. · If the flow readout shows "0,000" then the leak is inside the house.

Nonreturn valves use the mechanism to allow the medium only in the right direction. It has two openings; one inlet and the other outlet. A closing member separates the inlet and outlet staying in between. When the fluid enters the non-return valve through the valve inlet, the fluid pressure keeps the closing member open.

NON-RETURN VALVE ULTRA 20 WITT non-return valves for reliable protection against dangerous reverse gas flow. Flow-optimised valve system causes very low pressure drop at minimal noise emission. Every non-return valve 100% tested. Benefits a spring loaded non-return valve prevents back feeding of gases which could lead to unwanted gas mixtures

non-return valves are used to protect equipment and pipelines against dangerous reverse gas flow. Use is possible for applications according to EN 746-2

WITT non-return valves can be installed in the air or oxygen line as well as in the fuel gas supply, thus reducing acquisition and storage costs. WITT non-return valves are 100% tested

The gas non-return valves (check valves) are available in three sizes, DN 25, DN 32 and DN 50 with thread from 1/2" to 2" as well as special thread, in brass or stainless steel. Data sheets. GRS 25; GRS 32; GRS 50; GRS 25-VA; GRS 32-VA; GRS 50-VA; Details - Gas non-return valves. Heating furnaces.

In-line NRVs: This type of non-return valve uses a spring and the flow is allowed when the upstream pressure exceeds the spring tension. Again when the pressure goes below the pressure to overcome spring tension the flow is blocked. Folding Disc NRVs: Mainly used for gaseous or low-pressure liquid service, this type of non-return valves are made in a wafer body pattern.

Disc Check Valve prevent the overturn flow of release fluid in the closed method, hence recommended for guaranteed non return valve flow for any liquid & gas process. They are also proper for wide range of fluid purpose such as hot water, process lines, and condensate and water arrangement. Our accessible valve with disc and spring construction

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.

These valves are offered in 2 configurations: in-line ball check and totally guided disc with soft or hard seats. In-line ball check valves will be utilized in each vertical and horizontal line. The totally guided disc inline check valves should be supplied with a spring-assist closure once employed in horizontal lines.

Gas Safety Engineering Safety devices, gas non-return valves and gas hose couplings. All safety devices and gas hose couplings are design type-tested and are subject to constant production monitoring by neutral test institutes, such as BAM and UL.The safety devices in accordance with EN ISO 5175-2 (check valves and flashback-resistant gas non-return valves) are tested by BAM and approved by DVGW.
