공기 제어 밸브

Air Control Valves | Use Air Signals to Control Flow for Safe, Non-Electric Automation. Explore our range of air-piloted control valves. They use a low-pressure air signal to shift the main valve spool, controlling the flow path without any electrical power. This makes them the inherently safe and reliable choice for hazardous environments like chemical plants or mining, or in applications with high moisture. Find the right valve for your non-electric control system now.

이해 공기 제어 밸브 Mechanisms

How Air Control Valves Function

Air control valves, particularly pilot-operated types, use a small amount of air pressure (the pilot signal) to shift a larger internal spool or poppet. This action redirects the main airflow through different ports, controlling the operation of pneumatic cylinders, actuators, or other devices. This method allows for robust control without direct electrical input at the valve itself.

Key Features:

  • Pilot Actuation: Utilizes air pressure for shifting, suitable for hazardous areas or where electrical power is limited.
  • Spool or Poppet Design: Different internal mechanisms for various flow characteristics and sealing properties.
  • Port Configurations: Common types include 3-port/2-position (3/2), 5-port/2-position (5/2), and 5-port/3-position (5/3) valves for diverse control logic.
  • 수동 재정의: Often included for testing or manual operation during setup or emergencies.

공기 제어 밸브 Installation & Troubleshooting

설치 모범 사례:

  • Ensure correct port connections (inlet, outlet, exhaust, pilot ports) as per valve markings and schematics.
  • Use clean, dry, and appropriately regulated air for both main supply and pilot signals.
  • Install filters upstream to protect valve internals from contaminants.
  • Mount the valve securely in a position that allows for easy access to manual overrides and pilot connections if needed.
  • Use appropriate fittings and thread sealant to prevent leaks.

Common Troubleshooting Tips:

  • Valve Fails to Shift: Check pilot signal pressure and connection, main air supply, and for any mechanical obstruction or stuck spool. Ensure manual override (if present) functions.
  • Sluggish Operation: Insufficient pilot pressure, low main air pressure, undersized valve or tubing, or internal wear/contamination.
  • Continuous Air Leakage: Worn or damaged seals, loose fittings, or cracks in the valve body.
  • Incorrect Actuator Movement: Double-check port connections to the actuator.

Always de-pressurize and de-energize the system before any installation, maintenance, or troubleshooting.

공기 제어 밸브 자주 묻는 질문

The primary difference is the actuation method:

  • 솔레노이드 밸브: Are actuated electrically. An electric current energizes a coil (solenoid), creating a magnetic field that moves a plunger or spool to shift the valve. They are easily integrated with electrical control systems (PLCs).
  • Air Control Valves (Pilot-Operated): Are actuated pneumatically. A small air pressure signal (pilot signal) is applied to a port, which then shifts the main valve spool. They are ideal for environments where electricity is undesirable or unavailable, or for creating purely pneumatic logic circuits.

While both control airflow, their means of activation and typical application environments can differ significantly.

This notation describes the valve’s function:

  • The first number indicates the number of ports (air connections) the valve has.
  • The second number indicates the number of positions the valve spool can take.

For example:

  • 3/2-way valve: Has 3 ports and 2 positions. Typically used to control single-acting cylinders (one port to cylinder, one for supply, one for exhaust). Can be Normally Closed (NC) or Normally Open (NO).
  • 5/2-way valve: Has 5 ports and 2 positions. Commonly used to control double-acting cylinders (two ports to cylinder, one for supply, two for exhaust). Can be single air pilot (spring return) or double air pilot.
  • 5/3-way valve: Has 5 ports and 3 positions. Used for double-acting cylinders requiring a mid-position stop (e.g., center closed, center exhaust, center pressure).

The minimum pilot pressure is the lowest air pressure required at the pilot port to reliably shift the main valve spool. This value is specific to each valve model and is usually listed in its technical datasheet.

It’s crucial to ensure your pilot signal pressure meets or exceeds this minimum requirement. If the pilot pressure is too low, the valve may not shift completely, may shift sluggishly, or may not shift at all, leading to system malfunction. The minimum pilot pressure can also vary depending on the main line pressure in some valve designs.

Yes, many air control valves are designed for manifold mounting. A manifold is a base block with common supply and exhaust passages, allowing multiple valves to be mounted compactly side-by-side.

Benefits of manifold mounting include:

  • 공간 절약: Reduces the overall footprint compared to individually piped valves.
  • 간소화된 배관: Minimizes tubing and fittings, leading to a cleaner and less complex installation.
  • 설치 시간 단축: Fewer connections mean quicker setup.
  • 손쉬운 유지 관리: Individual valves can often be replaced without disturbing the entire manifold or extensive piping.
  • Centralized Connections: Common supply and exhaust ports simplify system plumbing.

To maximize the service life of air control valves:

  • Use Clean, Dry Air: This is the most critical factor. Install and maintain proper air filtration (e.g., particulate filters, coalescing filters, air dryers) to remove contaminants and moisture that can damage seals and internal components.
  • Operate Within Specifications: Ensure operating pressure, pilot pressure, and temperature are within the valve’s rated limits.
  • Proper Lubrication (if applicable): Some older or specific valve designs might benefit from lubricated air. However, many modern valves are designed for non-lube service. If using lubricated air, ensure the lubricant is compatible with valve materials and avoid over-lubrication.
  • 올바른 설치: Ensure secure mounting and proper piping to avoid stress on the valve body.
  • 정기 검사: Periodically check for leaks, listen for unusual noises, and ensure smooth operation.
