Product Overview
Anshore Wafer Butterfly Valves are compact, lightweight quarter-turn valves designed to regulate or isolate flow by rotating a disc within the valve body. Installed between pipe flanges and tightened with flange bolts, their wafer design allows easy installation in pipelines with minimal space requirements.

Key Features

• Construction: Bodies made from cast iron, ductile iron, stainless steel, or carbon steel paired with resilient seats of EPDM, NBR, or Viton for tight sealing and corrosion resistance.
• Design: Centered or concentric disc with 90° rotation for quick open/close, producing minimal pressure drop.
• Connection: Wafer style means the valve is sandwiched between pipe flanges without additional bolts, relying on flange bolts for securing the valve.
• Standards: Conforms to EN 593, API 609, ISO 5752, and face-to-face dimensions per EN 558 Series 20 ensuring interchangeability and performance.
• Sizes & Ratings: Commonly available from DN40 to DN400 (1.5” to 16”), pressure ratings PN10 to PN16 (Class 150).
• Temperature Range: Media temperature handling typically from -10°C to +120°C depending on seat material.
• Actuation: Operable by hand lever, gearbox, pneumatic or electric actuators for automatic or manual control.
• Applications: Widely used in HVAC, water treatment, irrigation, petrochemical, industrial processes, and pumping systems.

Benefits

• Easy to install and maintain in tight spaces
• Lightweight and cost-effective
