Series 30,000 Basic Configuration

Vanessa Rotary Process Valves, Triple Offset, Metal Seated, Vanessa Series 30,000 Basic Configuration

Vanessa Rotary Process Valves can be used for the most severe applications. The valve incorporates a metal to metal seat with a geometrically significant triple offset design, which gives bi-directional zero leakage and 90° non-rubbing rotation. Regardless of the size and pressure, Vanessa is capable of maintaining the same design principles and performance throughout. Vanessa valves provide a combination of performance, light weight and compact design and can be used for isolation and control for virtually all fluids.

In 1975, Vanessa was the first company to introduce the revolutionary metal-to-metal seating, quarter turn, triple offset, zero leakage valve technology into the market with the Series 30,000 Rotary Process Valve. This unique valve product covers a huge variety of applications in many different industries and has given Vanessa a worldwide reputation for quality and performance in a triple offset valve. Today Vanessa is the leading manufacturer of high technology rotary process valves.

Features & Benefits:

  • Torque generated resilient metal seal provides zero leakage performance, in compliance with API 598 and/or API 6D.
  • Quarter turn non-rubbing design is achieved by triple offset geometry, completely eliminating all seat to seal rubbing throughout the 90 degree rotation of the disc.
  • Stellite® hardfaced standard integral seat results in broader applications, longer valve life and less maintenance.
  • Duplex laminated seal ring for both WCB and CF8M valves offer a very high mechanical strength and high reistance to erosion and corrosion. Solid seal ring in various materials is offered for several severe applications.
  • Single-piece cast body, with face-to-face dimensions in accordance to ISO 5752, API 609 and ASME B16.10 provides interchangeability with gate, ball and plug valves.
  • Integral position indicators on the stem and on the top mounting flange ensure positive disc position indication, in accordance with API 609.
  • All metal construction translates into an inherently firesafe valve.
  • Long-length hardened bearings, with bearing protector extend cycle life.
  • Internally and externally retained, blowout prevention.
  • Anti blowout shaft protection in full compliance with API 609.
