SCH8O/DIN UPVC/CPVC Pneumatic Flange Ball Valve

Name: SCH8O/DIN UPVC/CPVC Pneumatic Flange Ball Valve
Brand: Zheyi Pipeline (Wuhan) Co., Ltd.

Among all types of valves, the pneumatic flanged ball valve has the fluid resistance. Even the reduced-bore type has relatively low fluid resistance. The valve body of the pneumatic ball valve is equipped with thrust bearings to reduce friction torque on the stem, ensuring smooth and flexible long-term operation. The valve seat offers sealing performance, made from elastic materials like PTFE, which enhances sealing capability as the medium pressure increases. Additionally, the stem sealing is reliable and resistant to damage. Due to the self-lubricating properties of the materials used and minimal friction loss with the ball, the pneumatic ball valve has a long service life. Springs between the ball, stem, and valve body help discharge static electricity generated during switching, ensuring safe usage.

UPVC / CPVC Pneumatic Flange Ball Valve

Double-acting · Spring-return · Full port · Flanged ends

The SCH80/DIN UPVC/CPVC Pneumatic Flange Ball Valve is an automated quarter-turn isolation valve engineered for remote on-off and throttling control in corrosive and high-purity fluid systems requiring flanged connections. Manufactured to ASTM SCH80 and DIN standards, this valve integrates a pneumatic actuator with a flanged 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 flanged ends comply with DIN PN10/PN16 or ANSI Class 150 drilling patterns, enabling direct integration into existing flanged piping systems without adapters. PTFE seats and seals deliver bubble-tight shut-off. The actuator mounting follows ISO 5211 standards. This valve is widely used in automated process control, chemical dosing, water treatment, and industrial manufacturing systems where flanged connections are required for secure, leak-proof installation.

Flanged Connections

DIN PN10/PN16 or ANSI Class 150 flanges provide secure, leak-proof integration into existing piping systems without additional adapters.

Automated Operation

Double-acting or spring-return actuators enable remote control, process automation, and fail-safe positioning without operator intervention.

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 & Thermal Resistance

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

Installation Guidelines

Flange connections: Use full-face EPDM or PTFE gaskets. Torque bolts evenly in cross pattern to 15–20 Nm.

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.

Orientation: Install with actuator in accessible position. For horizontal lines, stem should be vertical.

Testing: Cycle valve manually and pneumatically before placing in service.

Periodic maintenance: Inspect flange bolts and gaskets annually. Cycle valve quarterly to prevent seat sticking.
Critical Restrictions

Temperature: UPVC 60°C max · CPVC 93°C max. Do not exceed seat and gasket ratings.

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.

Flange bolts: Do not overtighten — cracking risk above 22 Nm for DN80 .

UV exposure: Use UV-stabilized material or apply protective coating for outdoor installations.

Actuator storage: Protect from moisture and debris. Store in clean, dry area.
Frequently Asked Questions

What flange standards are available?

The valve is available with DIN PN10/PN16 flanges (per DIN 2501) or ANSI Class 150 flanges. DIN flanges are standard for European and metric piping systems. ANSI flanges are available for North American and imperial systems. Specify the flange standard when ordering.

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.

These pneumatic flanged ball 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.
