SCH80 / DIN · PNEUMATIC ACTUATED

UPVC / CPVC Pneumatic Ball Valve

Double-acting · Spring-return · Full port · PTFE seated

The SCH80/DIN UPVC/CPVC Pneumatic Ball Valve is an automated quarter-turn isolation valve designed for remote on-off and throttling control in corrosive and high-purity fluid systems. Manufactured to ASTM SCH80 and DIN standards, this valve integrates a pneumatic actuator with a one-piece or two-piece ball valve body. The actuator is available in double-acting or spring-return configurations, providing fail-safe positioning. The full port design maintains line flow characteristics with minimal pressure drop. The valve body is available in UPVC for general chemical service and CPVC for elevated temperatures up to 93°C. PTFE seats and seals deliver bubble-tight shut-off. The actuator mounting follows ISO 5211 standards, enabling direct mounting and easy replacement. This valve is widely used in automated process control, chemical dosing, water treatment, and industrial manufacturing systems.

Bubble-Tight Shut-Off

PTFE seats provide a reliable seal against the chrome-plated or solid CPVC ball, ensuring zero leakage across the full pressure range.

Chemical Resistance

UPVC and CPVC bodies resist acids, bases, and salts. CPVC extends service to 93°C for hot corrosive media.

Full Port Flow

The ball bore matches the pipe internal diameter, providing unrestricted flow and minimizing pressure drop across the valve.

Installation Guidelines

Actuator mounting: Ensure ISO 5211 mounting pad alignment. Use correct coupling and bracket.
Air supply: Filtered, lubricated air at 4–8 bar. Use solenoid valve for remote control.
Solvent welding: Use primer and cement specific to UPVC or CPVC. Allow full cure.
Flange bolts: Use full-face gaskets. Torque evenly to 15–20 Nm in cross pattern.
Electrical connections: Verify solenoid voltage and wiring. Use conduit for protection.
Testing: Cycle valve manually and pneumatically before placing in service.

Critical Limits

Temperature: UPVC 60°C max · CPVC 93°C max. Do not exceed seat 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 with concentrated nitric acid (>15%) in UPVC bodies.
UV exposure: Use UV-stabilized material or apply protective coating.
Actuator storage: Protect from moisture and debris. Store in clean, dry area.

Frequently Asked Questions

What is the difference between double-acting and spring-return actuators?

Double-acting actuators require air pressure to both open and close the valve. Spring-return actuators use air to open and a spring to close (or vice versa), providing fail-safe positioning in case of air supply loss. Spring-return is preferred for emergency shutdown applications.

What air pressure is required for operation?

The actuator requires filtered, lubricated air at 4–8 bar. Lower pressures may result in insufficient torque for reliable operation. Higher pressures may exceed actuator torque rating and damage the valve stem. Always verify with the actuator torque chart.

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 seat 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.

SCH8O/DIN UPVC/CPVC Pneumatic Ball Valve Branchekendskab

Application in the chemical industry: Advantages of UPVC/CPVC pneumatic ball valves in corrosive fluid control

In the chemical and related industrial fields, the delivery and control of corrosive fluids (such as acids, alkalis, saline solutions, organic solvents, etc.) place strict requirements on valve materials. UPVC (unplasticized polyvinyl chloride) and CPVC (chlorinated polyvinyl chloride) pneumatic ball valves have become the preferred solutions for many key industries due to their excellent corrosion resistance, lightweight structure and automatic control advantages. The following are its typical application scenarios and core advantages:

1. Chemical and industrial water treatment
Industrial wastewater/industrial water treatment: UPVC/CPVC valves can withstand wastewater containing chlorine, fluoride and strong acids (such as sulfuric acid and hydrochloric acid), avoid electrochemical corrosion problems of metal valves, and extend service life.
Photovoltaic industry: In the manufacture of solar panels, it is used to control the precise delivery of etching solutions (such as hydrofluoric acid) to ensure that high-purity fluids are contaminated.
Electronic semiconductors: Suitable for ultrapure water (UPW) systems and chemical (such as ammonia, isopropyl alcohol) distribution to avoid metal ion contamination of wafer processes.

2. Energy and Metallurgy
Nuclear power plants: In cooling water and low-concentration radioactive wastewater systems, CPVC has better radiation aging resistance than ordinary plastic valves.
Metallurgical industry: Used in pickling lines (such as hydrochloric acid and nitric acid) and electroplating liquid pipelines, resistant to high temperature corrosion (CPVC can withstand media above 90°C).

3. Life sciences and public utilities
Pharmaceutical industry: In pharmaceutical purified water and water for injection (WFI) systems, UPVC/CPVC valves comply with FDA certification and have no risk of precipitates.
Drinking water (Safe Drinking Water): In municipal water supply systems, the inner wall of the valve is smooth and scale-free, eliminating secondary pollution such as lead and rust, and complies with NSF/ANSI 61 standards.

Summary of core advantages
The king of corrosion resistance: It can resist more than 90% of strong acids, strong alkalis and organic solvents, and its lifespan far exceeds that of metal valves.
Zero pollution risk: The material is inert, no metal ion precipitation, and fluid purity is guaranteed (such as semiconductor and pharmaceutical industries).
Lightweight and low cost: easy to install, maintenance cost is reduced by more than 50% compared with stainless steel valves.
