High-pressure gas fittings
Gas safety valve and gas rupture disc
SCHWERLL supplies high‑pressure gas (or liquid) safety valves with stable performance, compliant with DN6 and DN9 specifications and equipped with pipeline‑mounted overflow discharge ports. Our products meet international standards such as CE and ASME, and their testing is conducted by authorized laboratories in accordance with I.S.P.E.S.L. or ASME national codes. In China, if you require a calibration certificate that complies with the Chinese TS standard, please specify this when placing your order.

SCHWERLL offers high-pressure gas charging valves and gas charging valve manifolds. These valves (and manifolds) can be configured as integral components of standard accumulator assemblies, or installed as standalone valves or valve manifolds in pressure‑gas systems tailored to the specific process medium. Depending on application requirements—such as operating pressure, ambient temperature, and other parameters—customers may select from SCHWERLL’s range of specialized charging valves.

High-pressure nitrogen hose assembly
SCHWERLL supplies specialized high-pressure gas hoses for accumulator system nitrogen hose assemblies, nitrogen‑charging and pressurization carts, and other applications. These hoses are engineered and manufactured specifically for high‑pressure gas service, utilizing dedicated materials and incorporating a puncture‑resistant treatment on the rubber surface of the finished product. Additionally, the metal fittings should be selected with designs, sealing configurations, and thread types that are compatible with the operating gas pressures.

High-pressure discharge valve on the gas side
SCHWERLL liquid drain valves are typically installed at the bottom of gas cylinders or at the lowest point of a system. For certain horizontally mounted vessels, an internal stainless-steel flushing line may need to be pressurized. The standard product interface is G3/4–ISO 228 (the universally used connection size for gas cylinders). The design pressure is 350 bar, with a nominal diameter of DN 4 mm. Liquid drain valves for higher pressures are available, depending on the user’s operating conditions.

Valve block with one-way shut-off function
SCHWERLL valve block for the nitrogen side, featuring a one-way shut-off function: in the normal operating state, it remains open, allowing bidirectional nitrogen flow; when closed, nitrogen is permitted to flow only from the accumulator toward the nitrogen cylinder side. Utilizing this valve block significantly enhances charging efficiency in accumulator systems during inflation, thereby reducing installation and commissioning time.
