Actuator Handle: Handle Length 150-300 mm

Component Specifications

Definition

A mechanical interface component designed for manual operation of drain valve actuators, typically featuring ergonomic grip surfaces, torque transmission mechanisms, and mounting provisions for secure attachment to actuator stems or shafts. It enables precise manual control of valve opening/closing positions in fluid handling systems.

Working Principle

Converts rotational force (torque) applied by an operator into mechanical motion transmitted through the actuator stem to position the valve closure element, utilizing leverage principles to reduce required operating force while maintaining precise angular positioning.

Materials

Typically manufactured from corrosion-resistant materials: Stainless steel (AISI 304/316), aluminum alloys (6061-T6), or engineered polymers (glass-filled nylon, acetal) with surface treatments (anodizing, powder coating) for environmental protection.

Frequently Asked Questions

What is the purpose of an actuator handle on a drain valve?

It provides manual control interface for opening/closing drain valves, allowing operators to regulate fluid flow without requiring automated systems.

Are actuator handles interchangeable between different valve brands?

Interchangeability depends on mounting interface compatibility (square drive size, spline pattern) and torque requirements, though ISO 5211 standardization improves cross-brand compatibility.
