7 Essential Components of Pneumatic Valve Systems

Modern pneumatic systems achieve efficient fluid control through precise component coordination. As a valve manufacturer with 15 years of experience, Flowx explains the critical parts:

1.Actuator

○ Types: Piston/Diaphragm actuators

○ Operation: Compressed air drives valve stem movement

○ Flowx Advantage: ISO 5211 compliant, compatible with major actuator brands

2.Valve Body

○ Materials: Brass (food-grade)/316 Stainless Steel (corrosion-resistant)/PEEK (chemical environments)

○ Flow Control: Globe valves (precision)/Ball valves (quick action)/Butterfly valves (high-flow)

Flowx's Specialized Accessory Solutions

1.Solenoid Valves

○ Quickly switches air circuits to keep your pneumatic system running smoothly.

○ Voltage Options: 24VDC/110VAC/220VAC (±10% tolerance)

○ IP65 Rating: Ideal for humid/dusty environments

○ 30% Energy Saving: Coil temperature 15℃ lower than industry average

2.Limit Switches

○ Provides real-time feedback on the valve's open/close position.

(Explosion-proof Limit Switch, Operates safely in hazardous environments, equipped with explosion-proof flexible hoses for high-pressure, fire-resistant, and 

explosion-proof protection of the pneumatic system)

○ ATEX Certified: Ex d IIC T6 models available

○ Dual Contacts: ±0.5° positioning accuracy

○ LED Indicators: Visual status monitoring

3.Air Filters

○ Ensures clean air supply for stable valve operation and protects the actuator, extending its service life.

○ *5-Micron Filtration*: Complies with ISO 8573-1

○ Auto-Drainage: With manual override

○ Coalescing Filter: Captures 0.01μm oil aerosols

4.Positioner

○ Greatly enhances the valve's control accuracy.
