Who is Masoneilan?

Founded in 1882 by inventor William B. Mason, Masoneilan has been and continues to be a major innovator in the valve and process control industry. Masoneilan automated process control solutions are part of the portfolio of Masoneilan valve technology that has helped customers maintain efficient operations and protect process industry assets. The product portfolio includes rotary control valves, globe control valves, valve actuators, severe service valves, digital valve positioners, etc.

Masoneilan’s rotary control valves are known for their quality and durability, particularly the 35002 Camflex II Eccentric Plug Rotary Globe Control Valve. This valve effectively combines enhanced control performance, simplicity, and long-term reliability for a broad range of applications.

Setting the Standard

Unlike some valves in the industry, the Masoneilan 35002 Series Camflex II Eccentric Plug Rotary Control Valve is not an automated valve pieced together in a valve automation shop. Its thoughtful design enhances overall product integrity and reduces the risk of component failure and process upset.

Reliability Matters

The valve’s main design objectives (reducing friction, reducing drivetrain slop, and mitigating component wear) are accomplished through a standard and simplified design architecture that helps the valve reliably perform the basic functions of shutoff, throttling, and emission control over an extended lifetime.

With its eccentric rotating valve plug, the valve reduces two common valve limitations: excessive seal ring friction and high actuator forces.

Camflex seating mechanics and resulting long-term reliable shutoff offer the following benefits:

  • Reduced rubbing – greatly reduced friction and wear
  • Improved uptime – extended maintenance cycles
  • Reduced unplanned outages and production loss

Environmental Emissions Compliance

Unlike some control valves that require expensive specialized packing systems to satisfy low emissions standards, Camflex II Eccentric Plug Rotary Control Valves come standard with GE’s Masoneilan EF seal (Emissions Free seal) technology.

  • Standard at no extra cost
  • Meets global low-emissions standards requirements
  • Simple and reliable with long life
