PI Controls Europe Pneumatic Control Valves
High-precision 2-Way and 3-Way diaphragm-actuated pneumatic control valves engineered by PI Controls Europe. Built with premium Stainless Steel, Carbon Steel, and Cast Iron bodies to deliver exact linear and equal-percentage throttling for Steam, Thermic Fluid, and Water networks across the Middle East, Africa, and CIS.
Pneumatic Diaphragm Actuation & Construction
PI Controls Europe pneumatic control valves operate by using compressed instrument air across a heavy-duty rolling diaphragm opposed by calibrated return springs, translating air pressure variations into micrometer-accurate plug positioning.
Multi-Spring Diaphragm Actuator
High-thrust pneumatic diaphragm actuator designed for fast response, minimal hysteresis, and dependable process control.
- Action Modes: Direct Acting (Air-to-Close) & Reverse Acting (Air-to-Open)
- Signal Air Pressure: 0.2 to 1.0 kg/cm² (3-15 PSI) or 0.4 to 2.0 kg/cm²
- Diaphragm Material: Reinforced Nitrile / EPDM with nylon fabric
- Actuation Control: High-precision pneumatic positioning for critical loops
Heavy-Duty Valve Body Metallurgy
Cast and forged bodies designed for sustained thermal cycles, pressure spikes, and aggressive flow media.
- Body Materials: ASTM A216 WCB Cast Carbon Steel, CF8M (SS316), Cast Iron
- Trim Metallurgy: Precision machined SS304 / SS316 with Stellite hardening
- Packing: Self-adjusting chevron PTFE or pure flexible graphite rings
- Pressure Classes: ANSI Class 150 (up to 10 kg/cm²) & Class 300 (up to 20 kg/cm²)
2-Way & 3-Way Valve Architectures
Optimized hydrodynamic geometries engineered for pure throttling, high turndown ratios, and flow switching.
- 2-Way Valves: In-line flow modulation for steam headers, heat exchangers, and water lines
- 3-Way Mixing: Blending two incoming streams into a single regulated outlet
- 3-Way Diverting: Splitting a single inlet into two outlets for thermic fluid loops
- Connections: Flanged ANSI B16.5 RF Class 150 and Class 300
