BASIC STRUCTURE
TECHNICAL PARAMETERS
Nominal diameter: DN40~DN1000
Nominal pressure: 1.0~1.6MPa
Applicable temperature: -30C~+180C
Applicable media: strong acid (such as sulfuric acid, hydrochloric acid), strong alkali (such as sodium hydroxide), hydrofluoric acid, chlorine and other corrosive fluids
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
Sealing material: PTFE or fluororubber elastic sealing ring
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
APPLICATIONS
Industrial scenarios: fluid control in industries such as petrochemicals, electricity, pharmaceuticals, and food processing
Special media: harsh working conditions such as oxygen, liquid metals, and radioactive fluids
Automation systems: can integrate accessories such as solenoid valves and positioners to achieve remote or centralized control

WORKING PRINCIPLE
OPTIONAL ACCESSORIES
Feedback device
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
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.
Filter
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.
Manual device
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.
SOLVE INDUSTRY ISSUES
Chemical Industry
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.
Food and Pharmaceuticals
Challenges: High media hygiene requirements, cross contamination must be avoided.
Solution: Mirror polishing + full bore design.
Ocean
Challenge: High salt spray environment accelerates metal oxidation and seals are prone to failure.
Solution: Ultra-low carbon stainless steel + EPDM sealing ring.
