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, 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

VMV V9000 series GLOBE straight-stroke bellows control valve is developed by Newton’s professional R&D team. In view of the conventional control valve, packing is easy to wear, leak externally, poor adjustment regulating, bellows seal is not durable and other phenomena, VMV has collected much operational condition informatio and researched technically for the above phenomenon.Many tests have proved that the V9000 series can fully meet the users’ needs, especially applied in the petrochemical industry and high requirements for fresh air and other special conditions.

Long-term operation, maintenance-free to keep working
Zero leakage of valve stem during long operation cycles
Bellows’ operational service life >500,000 times

5.1 Single-seat control valve

①. Bellows anti-rotation Structure
The keyway on the valve stem is matched with the pin of the bellows sleeve. Forcing the bellows to move along the axis to prevent damage and increase the service life of the bellows.

②. Bellows failure detection structure
A pressure gauge or pressure sensor can be connected to the detection port on the valve bonnet for real-time monitoring of bellows leakage.

③. Single bonnet structure
Lower external leakage risk.

④. Thread + Pin Connection Structure
The plug and stem are closely connected, and there is no relative moving gap. Effectively prevent stem fatigue and fracture caused by the relative swing of the plug and stem.

⑤. Sealing gasket quantitative compression structure
Prevent the gasket from being overly compressed to achieve durable sealing without leakage.

⑥. Up-pressure valve seat structure
By loosening the valve bonnet bolts, the internal components of the valve can be removed one by one, allowing for quick maintenance and replacement of the valve seat and internal components on-site,thus saving the user’s maintenance time.

⑦. Bellows and flow channel separation structure
Prevent the medium from directly impacting the bellows, improve the service life of the bellows.

⑧. Double-guided valve plug structure
The valve core operates smoothly, not prone to vibration and sticking,ensuring higher regulating precision.cc

⑨. Bellows structure with protective armor
Protects the bellows during handling, installation, and operation. Without bonnet parts, more convenient and fast to replace.

⑩. Bellows external pressure bearing structure
Provide stable pressure load for bellows, reduce movement and increase the maximum allowable stress, thus improving the bellows service life and valve operation accuracy.

5.2 Balanced Single-Seat Bellows Control Valve

①. Wear-resistant piston ring seal structure
The wear-resistant piston ring still has self-lubricating at temperatures above 200°C, making the valve not easy to stretch and stick during the long period regulating process, maintaining a seal class above level IV .

②. Balanced single-seat structure
Low thrust overcomes the large pressure difference, has better performance of overcoming differential pressure.

③. Spherical valve plug structure
The throttling orifice is uniformly distributed on the surface of the valve core, allowing the medium to flow smoothly and stably, thus has higher regulating precision.
