SCH8O/DIN UPVC/CPVC Pneumatic Butterfly Valve

The pneumatic butterfly valve adopts a wafer-type design with a compact structure, small size, and lightweight design, making it convenient to install, transport, and maintain. It is driven by a pneumatic actuator that rotates the valve stem, enabling the disc to rotate quickly within the valve body by 90°, achieving rapid opening and closing with fast response. It precisely controls flow according to system requirements, providing stable and reliable throttling, cutoff, and isolation functions. The valve uses elastic sealing materials such as rubber or PTFE to ensure effective leakage prevention when closed. The pneumatic butterfly valve is suitable for various media such as water, oil, and steam and operates within a wide range of pressures and temperatures, meeting the demands of different piping systems.

UPVC / CPVC Pneumatic Butterfly Valve
Double-acting · Spring-return · Liner sealed · ISO 5211
The SCH80/DIN UPVC/CPVC Pneumatic Butterfly Valve is an automated quarter-turn flow control device engineered for on-off and throttling service in corrosive and high-purity fluid systems. Manufactured to ASTM SCH80 and DIN standards, this valve integrates a pneumatic actuator with a wafer or lug-style butterfly valve body. The actuator is available in double-acting or spring-return configurations, providing fail-safe positioning. The resilient liner — available in EPDM, PTFE, or Viton — provides bubble-tight shut-off across the full pressure range. The wafer and lug configurations allow for dead-end service and easy installation between standard flanges. The actuator mounting follows ISO 5211 standards. This valve is widely used in automated process control, chemical dosing, water treatment, and industrial manufacturing systems requiring lightweight, compact, and cost-effective flow control.

ISO 5211 Mounting pad
Liner Sealing
The replaceable EPDM, PTFE, or Viton liner provides a tight seal around the disc and flange faces, eliminating leakage paths and simplifying maintenance.
Automated Operation
Double-acting or spring-return actuators enable remote control, process automation, and fail-safe positioning without operator intervention.
Chemical Compatibility
UPVC and CPVC bodies resist a broad spectrum of acids, bases, and salts. Liner material can be selected to match specific chemical exposure.
Throttling Capability
The butterfly design allows for precise flow modulation across the 0–90° rotation range, providing control flexibility beyond simple on-off service.

Installation Guidelines
  • Wafer installation: Center the valve between flanges. Use appropriate flange bolts and nuts. Tighten evenly in a cross pattern.
  • Lug installation: Bolt directly to one flange for dead-end service. Use full-face gaskets on both sides.
  • Disc positioning: The disc should be in the closed position during installation to avoid damage to the liner.
  • Air supply: Filtered, lubricated air at 4–8 bar. Use solenoid valve for remote control.
  • Actuator mounting: Ensure ISO 5211 mounting pad alignment. Use correct coupling and bracket.
  • Testing: Cycle valve manually and pneumatically before placing in service.
Critical Restrictions
  • Temperature: UPVC 60°C max · CPVC 93°C max · Do not exceed liner rating.
  • Air pressure: Do not exceed 8 bar supply pressure. Actuator torque increases with pressure.
  • Not rated for steam service. Avoid rapid thermal cycling and pressure surges.
  • Do not use EPDM liner with hydrocarbon solvents, oils, or strong oxidizers.
  • PTFE liner has limited abrasion resistance — not recommended for slurries with high solids content.
  • UV exposure: Use UV-stabilized material or apply protective coating.
  • Do not operate the valve in the 5–85% open range for extended periods in abrasive media.
Frequently Asked Questions
What is the difference between wafer and lug styles?
Wafer style is installed between two flanges and held in place by flange bolts. It is lightweight and cost-effective. Lug style has threaded inserts on both sides, allowing the valve to be bolted directly to one flange for dead-end service and isolation of downstream piping.
How do I select the correct liner material?
EPDM is suitable for water, mild acids, and alkalis up to 80°C. PTFE is recommended for aggressive chemicals, solvents, and high-purity applications up to 93°C. Viton (FKM) is used for hydrocarbons, oils, and strong oxidizers up to 90°C. Always verify compatibility with your specific process chemistry.
Can this valve be used for throttling control?
Yes, with a positioner and appropriate control signal (4–20 mA or 0–10 V). The pneumatic actuator provides proportional positioning, enabling accurate flow control. However, throttling service may reduce liner life compared to on-off service.
What accessories are recommended?
Common accessories include solenoid valves for remote on-off control, positioners for throttling, limit switches for position feedback, and filter-regulator-lubricator units for air preparation. Accessory selection depends on the application and control system requirements.
These pneumatic butterfly valves serve chemical, metallurgical, photovoltaic, nuclear, lithium, semiconductor, food, pharmaceutical, automotive, and water treatment industries — handling acids, alkalis, ultrapure water, potable water, electronic grade water, and industrial wastewater.

Selection Guide for Pneumatic Butterfly Valves in Industrial Automation: How to Match Pressure, Temperature and Media?

In industrial automation systems, pneumatic butterfly valves are widely used in multiple industries due to their fast response, compact structure and easy control. However, different industries have different requirements for valve pressure, temperature and media compatibility. Improper selection may lead to valve failure, leakage or shortened life. The following are key selection points for different industries:

1. Pressure level matching
Pneumatic butterfly valves need to select appropriate design pressures (such as PN10, PN16, ANSI 150, etc.) according to the system working pressure:
Photovoltaic, Electronic Semiconductor: Usually low pressure (PN6~PN10), used for ultrapure water or gas delivery.
Metallurgy, Nuclear Power: Medium and high pressure (PN16~PN40), need to resist impact pressure, especially high temperature and high pressure steam or corrosive fluids.
Industrial Wastewater, Drinking Water: Normal pressure to medium pressure (PN10~PN16), water hammer effect needs to be considered.

2. Temperature adaptability
The valve body material (such as cast iron, stainless steel, fluorine lining) and sealing material (EPDM, PTFE, NBR) need to match the medium temperature:
Medicine, semiconductor: low temperature or normal temperature (-20°C~120°C), sterile grade materials (such as 316L stainless steel PTFE seal) are required.
Metallurgy, nuclear energy: high temperature (200°C~500°C), metal hard seal or special alloy valve body is required.
Photovoltaic: may involve extreme temperature difference, and weather-resistant materials are required.

3. Medium compatibility
The corrosiveness and particulate content of the medium determine the valve material and sealing solution:
Drinking Water, Industrial Water Treatment: requires no pollution, and EPDM or FDA-certified sealing materials are selected.
Industrial wastewater: containing acid, alkali or solid particles, requires fluorine lining (PTFE) or wear-resistant rubber seal.
Electronic semiconductor: ultrapure water or high-purity gas, the inner wall of the valve needs to be electrolytically polished to avoid particle precipitation.
Nuclear energy: radioactive media require all-metal sealing valves with special certification (such as ASME N grade).

Industry application examples
Photovoltaic: low-pressure and room-temperature ultrapure water transportation, emphasizing zero leakage and long life.
Metallurgy: high temperature and high dust environment, valves need to be wear-resistant and anti-stuck.
Medicine: high sterility requirements, valves need to be easy to clean (CIP/SIP compatible).
Nuclear energy: under extreme working conditions, valves need to meet seismic and radiation protection standards.
