Single Acting With Spring Return Penumatic Actuator Ball Valve With ISO Mounting

Core product positioning

An automated control valve that integrates fault safety protection and standardized installation. Single-acting spring-return pneumatic actuators are adopted. When the air source fails, they automatically return to the preset safe position (fully open or fully closed), and strictly follow the ISO 5211 installation standard to ensure rapid and precise connection with various actuators.

Technical specification parameter table

Core design features

1. Single-acting spring return mechanism

Fail-safe protection

Fault Closure (FC) : The spring-driven valve closes when gas is lost

Fault Opening (FO) : The spring-driven valve opens when gas is lost

Quick response: The spring release time is less than 2 seconds, ensuring rapid action in emergency situations

Low-power design: Only a single gas source control is required, saving energy consumption

2. ISO 5211 standardized installation

Universal interface: Ensures perfect integration with any actuator that complies with ISO standards

Quick replacement: The actuator and valve can be quickly separated for easy maintenance

Precise positioning: Standardized connections ensure the accurate opening and closing positions of the valves

3. High-performance pneumatic actuators

Compact design: Optimized interior space, more efficient torque output

Double-piston structure: It adopts a symmetrical piston design, ensuring smooth operation

Visual position indication: Clearly shows the open and closed status of the valve

Manual operation function: Standard manual override device is provided for convenient debugging and maintenance

Detailed explanation of performance advantages
