Nominal diameter: DN40~DN1000
Nominal pressure: 1.0~1.6MPa
Applicable temperature: -30C~+180C
Valve body material: ductile iron, WCB carbon steel, 304/316 stainless steel, the surface is fully lined with polytetrafluoroethylene (PTFE) or F46 fluoroplastic to form a corrosion-resistant isolation layer
Butterfly plate material: 304, 316L stainless steel
Connection form: wafer type or flange type, in line with GB/T9113, JB/T79 and other standards
Pneumatic actuator: single-acting (spring return) or double-acting piston type, air supply pressure 0.3~0.8MPa
Control mode: support ON-OFF type (with solenoid valve) or modulating type (with electric positioner), input 4~20mA signal to achieve flow control
The feedback device, also called limit switch, is a feedback device used for the stroke, size, and position of mechanical movement. The computer observes and controls the state of mechanical movement.
Solenoid valve is a basic component for controlling fluids and is used in industrial control systems to adjust the direction, flow, speed and other parameters of the medium.
A large amount of compressed air containing water enters the filter and moves in a centrifugal downward tilt. The entrained water is separated due to the reduced speed, and the clean air is discharged from the separator outlet.
The aluminum alloy anti-rust and anti-corrosion coating is more resistant to high temperatures. The manual device can be switched to manual control immediately on site in case of control failure.
Challenges: Highly corrosive media such as chlorine-alkali and sulfur recovery can easily cause valves to rust and fail.
Solution: 316L stainless steel valve body + metal seal, passed NACE MR0103 standard, corrosion-resistant.
Challenges: High media hygiene requirements, cross contamination must be avoided.
Solution: Mirror polishing + full bore design.
Challenge: High salt spray environment accelerates metal oxidation and seals are prone to failure.
Solution: Ultra-low carbon stainless steel + EPDM sealing ring.
