Product catalog summary
Overview: This document outlines the technical specifications for the pneumatic servocontrols of the 'SERM9' and 'SERM8' series, which are designed to convert pneumatic signals into linear movements for valve stems, suitable for two or three-way control valves.
Specifications: The series includes both direct-acting and reverse-acting servocontrols. Direct-acting models ('SERM9' – 'SERM8 A') retract the stem when air pressure is applied, while reverse-acting models ('SERM8' – 'SERM9 A') extend the stem. ATEX-certified valves are available, marked as II 2 GD c IIC X.
Air Consumption: Air consumption is specified for modulating servocontrols with an air supply at 2.07 bar (3.2 bar for SS2L), measured in nl/stroke for different models, with specific volumes detailed.
Components and Materials: A parts list includes materials such as carbon steel, NBR with fabric reinforcement, brass or aluminum, and AISI 303 stainless steel. Options for stainless steel caps and bridges are also available.
Dimensions and Codes: Tables provide overall dimensions and codes for the 'SERM9' and 'SERM9-A' series, detailing nominal signals, starting points, and dimensional parameters in metric and imperial units.
Notes: Dimensions 'L' and 'STROKE' may vary due to spring tolerances. Detailed measurements are provided for each model to ensure precise application and installation.
