Single-Point Connection Valve Assembly

Single-Point Connection Valve Assembly


Winn-Marion has the design and assembly expertise to customize a variety of body, trim, and seat materials to suit an extensive range of applications in industries ranging from chemical and petrochemical to refining, pulp and paper, and power.


Together with the Valv-Powr actuator, this assembly provides the benefits of high cycle life, a rugged construction, and an extremely compact and symmetrical design with a unique range of features and options. Specifically designed for fast, efficient operation of ball or butterfly valves, at a very economical cost.

The Jamesbury brand full port polymeric-seated flanged ball valve provides high flow capacity, and positive bi-directional shut-off for isolation and control applications. Polymeric-seated flanged ball valves are available in sizes 1/2" to 24" (DN 15 -600) in both full-bore and standard-bore designs that adhere to ASME B16.34 requirements. The valves meet over 30 industry standards and specifications. 

Jamesbury actuators are designed to maximize cycle life and improve process efficiency, and provide safe and trouble-free operation. The Valv-Powr actuator is suitable for all process applications because of its compact design. It offers several added corrosion treatments such as electroless nickel, hard anodized protection and TFE coating. 

Winn-Marion has the ability to offer a full array of valve monitoring and communication solutions to facilitate connectivity of on-off valves to your plant networks in order to allow better data collection for improved maintenance and decision-making. 

Key Advantages

  • Valves, actuators, and accessories may be purchased completely mounted from one source
  • Stainless steel linkage actuator has guided coupling to align top-works during assembly, and eliminate side load stress on stem seals for long life, clean environment and minimal maintenance
  • Superior control characteristics, coupled with tight shut-off capabilities, make Jamesbury valves ideal for a variety of on-off and control applications
  • Polymeric flexible lip-seat design offers tight shut-off in either direction and extended cycle life, expanded performance boundaries, and greater value
