Energy management die casting: gas regulator and valve bodies

EDT Diecasting Technology (Suzhou) casts zinc parts for gas control equipment. Parts in this category are judged on gas tightness: gas pressure regulator bodies and gas control valve bodies, where porosity has to be controlled across casting, machining and finishing to keep the seal reliable over the service life.

Typical parts in this category

• Gas pressure regulator — vacuum casting plus impregnation for controlled porosity and tightness.
• Gas control valve body — twin chambers cast in one piece with machined sealing faces and leak testing.

Process and quality control

Porosity and tightness are the governing characteristics. The route covers flow and venting review, vacuum casting, deburring, CNC machining, cleaning, resin impregnation and leak testing. Sealing faces, valve seats and threaded ports are finish machined for flatness and fit, and internal quality can be confirmed by sectioning or CT sampling. Materials and finishes meet SVHC (REACH) and RoHS 2.0 requirements, and the plant operates to ISO 9001, IATF 16949 and ISO 14001.

Industries served

Gas distribution and pressure regulation equipment, gas metering and detection devices, industrial combustion and thermal systems, and gas control components in new energy and storage systems.

Purchasing FAQ

Q：How is gas tightness assured?
A：Vacuum casting limits entrained gas, resin impregnation after machining seals interconnected micro-pores, and finished parts are leak or pressure-hold tested to customer standards, with sampling used to verify internal quality in production.

Q：Which environmental requirements apply to gas parts?
A：Materials and finishes need to meet SVHC (REACH) and RoHS 2.0 requirements, and manufacturing runs under an ISO 14001 environmental management system.
