VPA342V-1-01A: Pneumatic Control, Precision Direction Switching! Pilot-Operated Air Control Valve Enables Reliable Fluid Switching
2025-09-17
Core Product Advantages
Pure Pneumatic Control, Safe and Explosion-Proof
Operates without electricity, driven by air source pressure (pilot air) to actuate spool direction switching. Eliminates risk of electrical sparks, making it perfectly suitable for explosion-proof applications (e.g., chemical plants, mining, petroleum).
High Flow, Low Operating Force
Pilot-operated design uses low-flow pilot air to control high-flow main air paths. Features low operating force and high flow capacity (Cv value), capable of driving large actuators.
High Reliability Design
Valve body made of brass or stainless steel for corrosion resistance; spool and sleeve precision-ground with wear-resistant sealing materials, ensuring millions of cycles of service life.
Manual Override Function
Equipped with a manual operation device (push-pull or rotary type), facilitating debugging, maintenance during power failure, or emergency intervention to ensure system safety.
Flexible Interface Configuration
Wide range of interface specifications (e.g., 01A may indicate interface size), supports baseplate or tube mounting, adaptable to various pneumatic layout requirements.
Typical Application Scenarios
Explosion-Proof Areas: Pneumatic control of equipment in chemical plants, coal mines, oil and gas platforms requiring explosion-proof solutions.
Harsh Environments: High temperature, high humidity, strong vibration, and other conditions unsuitable for electronic components.
Safety Circuits: Serves as the final control element in safety systems, driven by air signals from safety valves or two-hand triggering devices.
Large Equipment: Controls large cylinders or acts as a main control valve, with pilot signals provided by small solenoid valves or manual valves.
Technical Parameters
Interface Specification: G1/8″ (example, subject to specific model confirmation)
Operating Pressure: 0.1–0.8 MPa
Pilot Pressure: 0.15–0.8 MPa
Operating Temperature: -5°C to +80°C
Sealing Material: NBR/FKM
Conclusion
The VPA342V-1-01A air control valve, with its pure pneumatic operation, high reliability, and environmental adaptability, serves as a “loyal guardian” for pneumatic control in special working conditions. It precisely controls fluid path switching via air signals, providing a safe and reliable solution for explosion-proof and harsh environments.
