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”.

Description

Description

Working Principle

Based on the differential density of steam and liquid.

Features

Valve body and bonnet are made of cast steel, forged steel.
All internal parts are made of stainless steel, and the wear allowance has been fully considered in the design of movable parts,which improves the service life of the steam trap.
Special flow channel design to achieve zero water hammer.
Patented flexible closing system and micron-level precision closing system double guarantee no steam leakage and long service life.
Pressure equalization pipe completely solves the air blockage.
Built-in filter makes the air trap work in a clean environment.
Choose different capacity curves according to the differential pressure, increase capacity.
Drain plug is designed at the bottom of the air trap to ensure that the internal water will be drained, to prevent floating ball from freezing damage in cold weather.
