Company

“Let our Valves create Maximum Value” —This is what the brand VMV stands for .

VMV Newton was founded in 1998 and committed to providing comprehensive solutions for steam and thermal energy systems.

Not just products service, but from the site survey, energy saving diagnosis, full range of product development, project landing, operation monitoring to from system solutions, all follow the principle of sustainable development.

We have also qualified with CE PED 0036, ISO9001, ISO14001, ISO45001,ISO15848,API624, EAC, TS A1, CCS certificates.

Who We Are

Corporate Responsibility

VMV Quality-first manufacturing

The development model of VMV Newton has initially transformed from a “traditional valve product manufacturer” to a “comprehen solution for system” service provider, achieving the full process service of “on-ite inspection, scheme design, intelligent manufacturing of a full range of products, and installation and landing”.

Equipment Part

Service Part

DF3 Silencer

The DF3 silencer is compact and is used to discharge to the steam trap outlet of the inlet condensate return line. It reduces the noise and water hammer problems caused by rapid cooling of flash condensate at the trap discharge outlet.
The main body of the silencer is made of SS304, the inner part is stainless steel, and a filter device is installed at the inlet.
