Pneumatic Control Valves Explained
The pneumatic control valve manipulates a flowing fluid, such as gas, steam, water, or chemical compounds to compensate for the load disturbance and keeps the regulated process variable as close as possible to the desired set point.
This type of valve with its classic globe body shape, which reflects its name, uses the variable area generated between the plug and seat to control fluid flow. It is very versatile offering reduced trim options as well as a variety of special trims for severe high pressure drop applications. This style of valve is easily adapted for use on cryogenic temperatures and for high temperature duties.

Specification & Design
Our specialist valve engineers work as alongside your team to assist in the design, specification and delivery of your valve and provide you with the application specific advice and up to date information.
Valveforce understand that the process requirements differ. Therefore this linear movement valve comes in both equal percentage and linear characteristics.
When it comes to materials, we can offer options for carbon steel as well as stainless steel body. For the trim material there are option for standard Stainless steel, Stainless steel alloy such as Monel, half stellite or full stellited trim for severe service applications to avoid flashing or cavitation and also soft material such as PTFE for tight shut off.
There are single stage trim option and also multi stage trim option for reducing noise.
Valveforce are an independent company therefore we can supply a whole range of pneumatic control valve from leading manufactures around the world. We offer highly competitive prices on a quality range to cover all pressure classes and temperature ratings. We offer these valves in both DIN and ANSI whichever type you need to make your plant running smoothly and efficiently.

Installation & Commissioning
Ensuring System Compatibility
Valveforce ensures that the selected pneumatic control valve is suitable for your specific application. We consider factors such as the type of medium (steam, water, air, etc.), pressure, temperature, and flow rate requirements. Our experts choose valve materials compatible with your process fluid to prevent corrosion and degradation, ensuring long-term durability.
Proper Sizing for Efficient Operation
Valveforce understands that correct sizing is crucial for efficient valve operation. We use flow coefficients (Cv) and other relevant parameters to match the valve size with your system's flow requirements. This prevents issues such as poor control from an oversized valve or inadequate flow handling from an undersized valve.
Optimal Orientation and Location
Our team installs valves in the correct orientation as indicated by the manufacturer, ensuring proper operation and longevity. We strategically place valves for easy access during maintenance and protect them from potential damage or extreme environmental conditions.
Ensuring Air Supply Quality and Pressure
Valveforce ensures your air supply is clean, dry, and at the correct pressure. Contaminated or moist air can damage actuator components, so we implement measures to maintain air supply quality. We also verify that the air supply pressure meets actuator requirements, ensuring reliable valve operation under all conditions.
Electrical and Control System Integration
For valves with solenoids or other electrical components, Valveforce ensures electrical supply and control signals are compatible and correctly integrated with your control system. Proper calibration of control loops is essential for accurate valve operation, and our experts handle this with precision.
Verifying Pressure and Temperature Ratings
Valveforce verifies that the pressure and temperature ratings of your valves meet or exceed the maximum prescribed design conditions in your system. This ensures the valves can handle high-pressure or high-temperature scenarios without damage or catastrophic defects.
Leakage and Environmental Considerations
We select the appropriate valve class based on allowable leakage rates, balancing safety and efficiency. Valveforce also considers environmental regulations, especially for applications involving hazardous or toxic fluids, ensuring compliance and protection.
Adhering to Best Installation Practices
Valveforce follows best practices for piping installation, ensuring proper alignment to avoid stress on the valve body. We use the correct type of gaskets and bolts for flanged connections and avoid valve positions that could trap pockets of liquid or gas, preventing damage and ensuring stable valve behavior.
Overhaul & Repair
Wear and Tear
Our expert team assesses and addresses wear on valve components, replacing or repairing parts like valve seats, stems, and actuator diaphragms to prevent leaks and restore performance, extending the life of your valves.
Air Supply Issues
We diagnose and rectify air supply problems, from contamination to insufficient pressure, ensuring your actuator receives the clean, consistent air supply needed for accurate valve control.
Diaphragm Failure
Valveforce tackles diaphragm failures with high-quality replacements resistant to aging, overpressure, and chemical degradation, ensuring reliable control over valve operations.
Sticking or Binding
We provide thorough cleaning and maintenance to eliminate dirt, scale, or corrosion buildup, ensuring your valve stems and actuators move freely, without obstruction.
