SS316 Wafer Butterfly Valve with EPDM Seat & Gear Operator | OEM Customization

Tianjin Worlds Valve Co., Ltd. offers a high-quality Wafer Butterfly Valve constructed entirely from stainless steel 316 (SS316) for both body and disc, providing excellent corrosion resistance in demanding environments. This valve is operated by a worm gear actuator (turbine head) , delivering smooth, high-torque manual control suitable for frequent operation and larger line sizes. The seat is made of EPDM (ethylene propylene diene monomer), offering reliable bubble-tight sealing for water, mild chemicals, and general industrial fluids. The stem is manufactured from SS431 stainless steel, ensuring good wear resistance and torque transmission.

Introduction:

The compact wafer-style body installs directly between standard pipeline flanges using through-bolts, saving space and reducing installation costs. All major components—body, disc, seat, and stem materials—are customizable to meet specific application requirements. For example, discs can be upgraded to duplex or super duplex stainless steel, seats can be changed to NBR, Viton, or PTFE, and stems can be adapted to different alloys based on media and temperature conditions.

As a trusted China-based OEM manufacturer, we deliver consistent quality, flexible customization, and international certifications to meet your project specifications.

Key Features & Advantages:

1. All-SS316 Construction for Superior Corrosion Resistance

  • Full 316 Stainless Steel: Both body and disc are cast from SS316 (CF8M equivalent), offering excellent resistance to pitting, chlorides, and general corrosion in water, seawater, and many chemical environments.

  • Long Service Life: The material’s durability reduces maintenance frequency and extends valve lifespan in aggressive applications.

  • Hygienic Option: SS316 is easy to clean and suitable for food, beverage, and pharmaceutical services with appropriate seat materials.

 

2. Worm Gear Operation for Effortless Control

  • High Mechanical Advantage: The gear operator provides smooth, low-effort manual opening and closing, ideal for valves from DN80 upward.

  • Self-Locking Design: The worm gear mechanism holds the disc securely in any position without creeping, ensuring stable flow regulation.

  • Visual Position Indicator: Clear open/close indication allows operators to verify valve status at a glance.

 

3. EPDM Seat for Reliable Sealing

  • Bubble-Tight Shut-Off: EPDM elastomer provides excellent sealing performance for water, air, and mild chemicals.

  • Temperature Range: Suitable for operating temperatures from -20°C to +120°C.

  • Good Weathering Resistance: EPDM resists ozone, UV, and aging, making it suitable for outdoor installations.

 

4. Complete Material Customization

  • Disc Options: Duplex, super duplex, aluminum bronze, or PTFE/PFA-coated discs.

  • Seat Options: NBR (oil resistance), Viton (aggressive chemicals), PTFE (high-purity/wide temperature).

  • Stem Options: SS304, SS316, Monel, Hastelloy.

  • Body Options: Carbon steel, SS304, or other alloys as required.

 

5. Compact Wafer Design for Easy Installation

  • Space Saving: The wafer body installs between flanges without additional flange connections, reducing weight and footprint.

  • Quick Bolt-Up: Align and secure with through-bolts; no special tools needed.

  • Interchangeable Dimensions: Face-to-face per ISO 5752 / EN 558 ensures compatibility with standard piping systems.
