Quarter Turn & Linear Actuators

A quarter turn actuator is used when a system uses air, liquid, or electricity. A linear actuator has force applied in a linear way as opposed to rotary, such as a motor.
BRAY
Bray quarter turn

Bray offers two handles for on-off and throttling service – one for resilient seated valves from 1"-12" (25mm-300mm), and a high torque handle for high pressure valves from 2 1/2"- 8" (65mm-200mm). These quarter turn handles have a locking spring and a directional pointer for valve disc position indication. Bray also offers the Series 4 quarter-turn stainless steel gear operator for manual control of valve position. The weatherproof stainless steel housing is ideal for applications in highly corrosive environments as well as in breweries, pharmaceutical and sanitary industries.

Bray Series 70

  • Rugged, electric actuators for rotary valves
  • 300 to 18,000 lb-in output torque
  • Waterproof (nema 4, 4x, Ip 65)

Bray Controls' years of proven success in electric actuation, combined with innovative engineering, has produced the Series 70. the Series 70 features on-off or modulating control. this red, round electric actuator for rotary valves delivers highly reliable service. Bray's unique, customer–friendly designed control center has many advantages over present industry standards including:

  • UL,CSAandCEcertificationof most units
