Bailey Birkett G4 Pressure Reducing Valve - Fig 2044

Introducing the Pister BK3 Carbon Steel 3-Way High-Pressure Ball Valve, expertly designed for superior performance and durability. This robust valve features a carbon steel ball and stem, POM seats, and an NBR seal, ensuring optimal sealing and reliability under high pressure. Paired with the Valbia 85 series ISO direct mount quarter-turn electric actuator, this product offers a techno-polymer housing with IP67 protection for enhanced durability in various environments. The actuator is equipped with a manual override and visual position indication for added convenience. It includes two limit switches for remote indication of open and closed positions, alongside an electronic torque limiter for precise control. To prevent condensation, the internal anti-condensation heater ensures exceptional reliability, while PG11 electrical connections simplify installation. Our mild steel mounting kit and drive adaptor are included for straightforward fitting. All components are fully assembled and rigorously function tested for guaranteed performance. **Size Range**: Available in 1/8” to 2” **Valve Options**: Choice of stainless steel body and trim. **Port Options**: L-port or T-port configurations. **Operating Voltages**: Options available at 12 Volt AC/DC, 24 Volt AC/DC, and 110/240 Volt AC. For actuator choices, we offer: - On/Off (Fail Fixed) - On/Off with Battery Back-Up (Fail Close or Fail Open) - Positioner with 4 to 20 mA and 0 to 10 Volt DC signal - Battery Back-Up and Positioner (as previously detailed) Alternatively, consider the Valbia 86 series actuator, featuring an aluminium enclosure with all options outlined above.

The Resideo DH300 Pressure Sustaining Valve is designed to precisely regulate pressure on the inlet side. These valves are essential in applications where a specific inlet pressure must be maintained, such as in limiting pressure within the inlet supply network or in transitional links between supply networks and high-demand users. Their compact design makes them particularly suitable for installations in confined spaces, such as ducts. The DH300 is perfect for both commercial and industrial applications, aligning with its specified parameters.
