Pneumatic Valves and Actuators

What is a Pneumatic Actuator?

A pneumatic actuator or valve is a mechanical device that converts compressed air energy into motion, either linear or rotary. They are used in automated systems to control valves, dampers, or other equipment, and are common in industries for their reliability and use of compressed air.

Pneumatic valves deliver precise control of air and gas flow in industrial automation systems. Designed for reliability and efficiency, they enhance performance in actuators, cylinders, and process control applications, making them ideal for manufacturing, weighing, and automated systems.

Types of Pneumatic Valves

Directional Control Valves

These valves control the direction of air flow in pneumatic systems:

• 2-Way Valves: Simple on/off control
• 3-Way Valves: Direct air to one port while exhausting another
• 4-Way Valves: Control double-acting cylinders
• 5-Way Valves: Advanced control with multiple flow paths

Flow Control Valves

Regulate the speed of pneumatic actuators by controlling air flow rate:

• Meter-in control for extending speed
• Meter-out control for retracting speed
• Adjustable for fine-tuning operation

Pressure Control Valves

Maintain consistent pressure in pneumatic systems:

• Pressure regulators for consistent supply pressure
• Pressure relief valves for system protection
• Pressure sequence valves for multi-stage operations

Pneumatic Valve Applications

• Cylinder Control: Precise positioning and movement of pneumatic cylinders
• Automated Filling: Control of filling heads in LPG and liquid systems
• Material Handling: Actuation of grippers, clamps, and transfer mechanisms
• Process Control: Flow control in chemical and manufacturing processes
• Weighing Systems: Gate and valve control in batching applications

Advantages of Pneumatic Systems

• Clean and safe energy source
• Fast response times
• Simple and reliable operation
• Intrinsically safe for hazardous environments
• Low maintenance requirements
• Cost-effective for many applications

Solenoid Valves

What is a Solenoid Valve?

A solenoid valve is an electrically operated valve that controls the flow of a liquid or gas. It works by using an electromagnetic coil to move a plunger, which opens or closes an orifice to start or stop the flow through the valve body.

We offer high-quality solenoid valves with versatile coil options including 24VDC, 12VDC, 6VDC, and 220VAC. These valves provide reliable control of liquids and gases in industrial automation, weighing systems, and process applications, ensuring precision, efficiency, and long-lasting performance.

How Solenoid Valves Work

When electrical current is applied to the solenoid coil, it creates a magnetic field that moves an internal plunger or armature. This movement either opens or closes the valve orifice, controlling fluid flow. When power is removed, a spring typically returns the valve to its default position.

Types of Solenoid Valves

Normally Closed (NC)

The valve is closed when de-energized and opens when power is applied. This is the most common configuration for safety and energy efficiency.

Normally Open (NO)

The valve is open when de-energized and closes when power is applied. Used when flow must continue during power failures.

Bistable or Latching

Maintains position after a power pulse, reducing energy consumption. Requires pulse in opposite polarity to change state.

Solenoid Valve Configurations

• 2-Way Valves: One inlet, one outlet for simple on/off control
• 3-Way Valves: Divert flow between two outlets or from two inlets
• 4-Way Valves: Control reversible operations

Voltage Options

We supply solenoid valves in various voltages to meet your system requirements:

• 24VDC: Most common for industrial automation and PLC control
• 12VDC: Battery-powered and mobile equipment applications
• 6VDC: Special applications and low-power systems
• 220VAC: Direct line voltage operation

Solenoid Valve Applications

• LPG Systems: Cylinder filling control and emergency shutoff
• Chemical Dosing: Precise liquid injection in process control
• Washing Systems: Water and detergent control
• Compressed Air: Air line control and blow-off systems
• Irrigation: Automated water distribution
• Medical Equipment: Precise fluid control in healthcare devices

Selecting the Right Valve

Key Selection Factors

Choose valves based on these critical parameters:

Media Type

• Gas, liquid, or steam
• Chemical compatibility with valve materials
• Viscosity and particulate content

Pressure Rating

• Operating pressure range
• Maximum allowable pressure
• Pressure drop across the valve

Flow Rate

• Required flow capacity (Cv factor)
• Port size and orifice diameter
• Response time requirements

Environmental Conditions

• Operating temperature range
• Ambient conditions and exposure
• Electrical classification (hazardous areas)

Material Selection

Valve body and seal materials must be compatible with the process media:

• Brass: General purpose for air, water, and light oils
• Stainless Steel: Corrosive media and food/pharmaceutical applications
• Plastic (PVC, PP): Chemical resistance and cost-effectiveness
• Aluminum: Lightweight applications with corrosion resistance

Valve Maintenance

Preventive Maintenance Practices

• Regular inspection for leaks and damage
• Cleaning of valve internals as recommended
• Testing of solenoid coils for electrical continuity
• Replacement of seals and O-rings on schedule
• Lubrication of moving parts where specified

Common Issues and Solutions

• Valve Won't Open: Check electrical supply, coil continuity, and pilot pressure
• Leaking: Inspect seals, clean valve seat, check for damage
• Slow Response: Verify supply pressure, check for contamination
• Overheating: Ensure correct voltage, check for mechanical binding
