SCH80 · DIN · TWO-PIECE

UPVC / CPVC Ⅱ Ball Valve

Two-Piece Body · Full Port · Blow-Out Proof Stem

The SCH80/DIN UPVC/CPVC Ⅱ Ball Valve is a two-piece, full-port isolation valve designed for demanding corrosive and high-purity fluid applications. The two-piece body construction allows for in-line maintenance without removing the valve from the pipeline. Manufactured to ASTM SCH80 and DIN dimensional standards, this valve provides enhanced mechanical strength and pressure retention. The UPVC variant serves general chemical service, while the CPVC version extends operational capability to 93°C for hot corrosive media. PTFE seats and seals deliver bubble-tight shut-off across the full pressure range, and the blow-out proof stem design ensures safe operation under pressure.

Two-Piece Body Design

● In-line maintenance

● Blow-out proof stem

● PTFE seated

● Lockable handle

◆

Two-Piece Serviceability

The two-piece body design enables seat and seal replacement without removing the valve from the pipeline, reducing maintenance downtime in continuous processing environments.

◆

Chemical Inertness

UPVC and CPVC materials resist a wide range of acids, bases, salts, and oxidizing agents. The inert polymer construction prevents fluid contamination and maintains system purity.

◆

Blow-Out Proof Stem

The stem is retained by a mechanical stop that prevents accidental ejection under pressure, ensuring operator safety and system integrity in high-pressure applications.

◆

Full Port Flow

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

Installation & Operation

Solvent weld connections: Use primer and cement specific to UPVC or CPVC. Observe cure times before pressurization.

Threaded connections: Apply PTFE tape to male threads only. Tighten hand-tight plus one full turn.

Flanged connections: Use full-face gaskets (EPDM/PTFE). Torque bolts evenly in cross pattern to 15–20 Nm.

Orientation: Install with stem vertical for horizontal lines. Ensure handle swing clearance.

Actuator mounting: Verify torque compatibility. Use approved mounting bracket and coupling.

Periodic operation: Cycle the valve quarterly to prevent seat sticking in low-use applications.
Safety & Restrictions

Do not exceed 60°C for UPVC bodies. CPVC max 93°C continuous.

Not rated for steam service. Avoid rapid thermal cycling.

Do not use with concentrated nitric acid (>15%) in UPVC.

Avoid pressure surges exceeding 1.5× rated working pressure.

Do not use petroleum-based lubricants on stem or seats.

Protect from prolonged UV exposure — use UV-resistant coating or shade.

Never force the handle beyond the mechanical stop.
Troubleshooting Quick Reference

▶ Handle difficult to turn

PTFE seat compression or media crystallization. Cycle the valve 3–4 times. If resistance persists, check stem seal lubrication. Avoid over-torquing.

▶ Leakage from stem area

Tighten stem gland nut incrementally. Replace O-rings if leakage continues. For hot service, verify O-ring material compatibility with fluid temperature.

▶ Valve does not seal in closed position

Inspect PTFE seats for wear or deformation. Replace seats if worn. For abrasive media, consider seats with reinforced PTFE.

▶ Cracking at connection points

Over-torquing of threaded or flanged connections. Verify torque values. Replace cracked components immediately.

These Type II ball valves are deployed across chemical, metallurgical, photovoltaic, nuclear, lithium, electronic semiconductor, food, pharmaceutical, automotive, and industrial water treatment industries for handling acid-alkali liquids, ultrapure water, potable water, electronic grade water, and industrial wastewater pipelines.
