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
  • High regulating precision
  • Fast response speed
  • Convenient and quick on-site valve maintenance
  • Wide temperature range(-196℃~588℃)

VMV equipped with either pneumatic diaphragm actuator or electric actuator according to the user’s on-site energy

5.1 Single-seat control valve

V9000 SERIES BELLOWS CONTROL VALVE Structure And Characteris1

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

V9000 SERIES BELLOWS CONTROL VALVE Structure And Characteris2

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.
