SPDA Series: Designed for Stream-Flo Crown Gate Valves

The SPDA actuator series embodies our commitment to operational excellence, offering a reliable, efficient solution tailored for Stream-Flo Crown gate valves. This focused approach ensures that our customers benefit from a cohesive system that enhances performance and reliability without the need for third-party valve integration.

Product Features

  • Fail-safe actuation: the SPDA is designed to safely close the gate valve upon loss of pneumatic pressure.
  • Bi-directional valves: Stream-Flo valves offer a bi-directional gate, which allow reversing direction of flowline without impacting valve operation.
  • Adaptable for use on other manufacturers’ valves: The SPDA actuator bonnet can be adapted to work on valves from manufacturers. The actuators are designed to allow for the maximum available stroke on the market.
  • Corrosion protection: The SPDA actuator is corrosion resistant against environmental conditions. Critical internal and external parts are either stainless steel or coated to maintain a clean actuation medium and smooth operation.
  • Over-pressure protection: A pressure relief valve is included in the actuator assembly to protect operators and the actuator against over pressurization.
  • Metal-to-metal backseat: The gate valve design offers a metal-to-metal backseat, which allows for packings to be replaced whole the valve is in service.
  • Reliable bonnet seal design: The bonnet includes a grease
    fitting to ease of lubricating the valve body. A tattletale weep port above the packing is included in the bonnet as a visual indication of the stem seal integrity.
  • Ease of maintenance: The SPDA assembly includes few simple components, which makes it easy to maintain and inspect. An upper seal cartridge houses non-metallic seals and is removable for ease of seals replacement.
