Key Features & Advantages：

1. Full PTFE Encapsulation – Zero Metal Contact & Maximum Chemical Resistance

• SS Disc is 100% encapsulated in virgin PTFE, eliminating any metal contact with the process media.

• Resists 98% sulfuric acid, chlorine, hydrochloric acid, solvents, and caustic soda across pH 0–14.

• PTFE is inert to most organic and inorganic acids and alkalis, with only molten alkali metals posing a threat.

• PTFE seat provides exceptionally tight shutoff with 0 leakage.

 

2. PTFE-Encapsulated Stainless Steel Disc – Strength Meets Corrosion Immunity

• Stainless steel core provides mechanical strength, while the PTFE encapsulation protects against chemical attack.

• All wetted surfaces are PTFE – no metal exposure to the line media.

• Low coefficient of friction (0.02–0.10) reduces operating torque and wear.



3. Pneumatic Actuator – Fast, Reliable Automated Control

• Double-acting or spring-return configurations available.

• Rapid on/off or modulating control for automated systems.

• Integrates with PLC, DCS, or SCADA via solenoid valves, limit switches, and positioners.

• Spring-return models provide fail-safe operation upon air supply failure.



4. Lug Body – Dead-End Service & Easy Installation

• Threaded lug inserts enable direct bolting to a single flange – ideal for end-of-line isolation.

• Bi-directional dead-end service at full rated pressure.

• Compatible with EN 1092, ANSI B16.5, and AS2129 flanges.



5. ISO 5211 Direct Actuator Mounting

• Standardized mounting interface enables direct attachment of pneumatic actuators without custom brackets.

• Allows quick field swapping between manual, electric, or pneumatic actuation.



6. Wide Temperature & Pressure Range

• Operating temperature: -35°C to +200°C.

• Pressure ratings: PN10/PN16/Class 150/Class 125/JIS5K/JIS10K...

• Size range: DN50 to DN900 (2″ to 36″) .



7. Fully Customizable OEM/ODM Solution

• Body materials: Ductile iron, WCB, carbon steel, CF8, CF8M.

• Disc: PTFE-encapsulated stainless steel (standard); other core materials available.

• Actuator: Double-acting, spring-return, electric, or manual gear.

• Flange standards: EN 1092, ANSI B16.5, AS2129, JIS.

• Certifications: ISO 9001, CE, UKCA, WRAS, ACS available upon request.
