2-way control valves with electric and pneumatic actuators made of carbon steel ACTA series P133

Overview

ASTA P100 is a single-seat two-way control valve, controlled by electric or pneumatic drives, designed for precise remote regulation or shut-off of the flow of the working medium.

Design Features

  • Various types of valve seals (PTFE or metal-to-metal)
  • A pressure-balanced version of the valve is available, allowing the use of low-power actuators
  • The shut-off and control surfaces of the plunger are spaced in different planes, which reduces wear on these surfaces and extends the service life of the valve
  • Self-sealing spring-loaded chevron gland assembly
  • Mechanical strengthening of the stem with subsequent polishing and lubrication to reduce friction and increase the service life of the gland assembly
  • Two stem guides to increase the accuracy of plunger positioning and reduce the impact of high pressure during its movement
  • A repairable design that allows changing the valve's throughput capacity during its maintenance.

Options on request

  • Vacuum valve design
  • Stelliting of internal parts
  • Feed valve
  • Various designs of valve flange sealing surfaces (versions C, L, D, M, etc.)
  • Electro-pneumatic positioner with standard 4...20 mA control, as well as with additional options (feedback, HART protocol, PROFIBUS, explosion protection, etc.)
