SAFETY SHUT OFF VALVE

INTRODUCTION

 

Safety Shut Off Valve “SSOV” pneumatic actuator series was engineered and is manufactured to provide maximum torque output with minimum supply pressure.

Simplicity, reliability and economy being at the top of the list of design parameters.

The “SSOV” actuator is suitable for any quarter turn application such as ball, plug, butterfly valves or dampers, in both On-Off and Modulating heavy duty service.

FEACHURE

 

  • Designed to be used in natural gas pressure reduction stations for safety purpose.
  • Work with pressure of line.
  • Upon request, it can be used for different fluid by operating with an external gas pressure source.
  • Valve is a complete package with actuator and control system.
  • It can adjust to the requested values for #150 #300 #600 pressure classes.
  • It can modify for different climate and site conditi

SPRING RETURN ACTUATOR

INTRODUCTION

The low pressure pneumatic spring return actuator series was engineered and is manufactured to provide fail safe operation for any quarter turn application such as ball, plug, butterfly valves or dampers, in both On-Off and Modulating  heavy duty service.

Simplicity, reliability and economy are at the top of the list of design parameters.

The spring module incorporates up to three springs, fully encapsulated in a factory-welded cartridge. This ensures safety to personnel and ease of assembly.

FEACHURE

  • Totally enclosed, weatherproof housing in fabricated carbon steel for maximum strength.
  • Canted scotch yoke actuators are ideally suited to the larger valve sizes where high break away torques are required or for valves with high working pressure
  • External travel stops for precise angular stroke adjustment between 85° and 95°
  • Jackscrew manual override. Hydraulic manual override special version
  • The spring return pack incorporates up to three springs, fully encapsulated in a factory welded cartridge: this ensures safety to personnel and simplifies assembly
  • The spring action can be easily changed in the field from to close in to open or vice versa (modular design)
  • solenoid valves - explosion proof, ‎intrinsically safe and/or weatherproof
  • control valves, flow regulators,‎quick exhaust valves
  • positioners  - pneumatic or ‎electro pneumatic
