About this item

  • STAINLESS STEEL DISC DURABILITY: This butterfly valve features an AISI304 stainless steel disc and GGG-40 cast iron body, delivering excellent corrosion resistance and long-term performance in industrial environments.
  • PRECISE FLOW CONTROL FUNCTION: The butterfly valve uses a quarter-turn disc and EPDM gasket to regulate liquid or gas with accuracy. Ideal for stopping, throttling, or starting flow with consistent sealing.
  • WAFER TYPE CONNECTION DESIGN: With a compact wafer body and protruding ears, this butterfly valve installs easily between flanges using bolts and nuts, aligning with EN 1092-1 standards.
  • THERMAL AND PRESSURE RESILIENCE: Operating at PN16 and withstanding temperatures up to 120°C (248°F), this butterfly valve is engineered for reliability in high-demand HVAC, water, or chemical systems.
  • ACTUATOR-READY BUTTERFLY VALVE: This butterfly valve supports both manual handles and automated systems using pneumatic or electric actuators, providing flexible integration for industrial automation needs.



Product Description

UNOX VALF

What is Wafer Type Butterfly Valve?

Butterfly Valves; It performs the on-off operation by rotating discs made of nickel, stainless or different materials (AISI304, AISI316, AL-BR) fixed around a shaft in the center. Butterfly valves perform the function of starting, slowing down or completely blocking the flow of liquid or gas by compressing the disc around the shaft with rubber or plastic gasket. It is the equipment used to stop, regulate or start the flow, which has a flap that can make a quarter turn around its own axis and a sealing gasket.

How Does a Wafer Type Butterfly Valve Work?

Wafer type butterfly valves are valve type with protruding ears that cover the whole body, designed to match the bolt holes on the flange to which it will be connected. It is mounted between two flanges by fixing with bolts, studs and nuts. This makes it impossible to disconnect only one side of the piping system from the valve. In addition to providing manual control, it is also suitable for use by mounting pneumatic actuators and electric actuators.

It is placed between the pipe flanges and the flange bolts surround the valve body. It is easy to install but cannot be used as an isolation valve. In addition to providing manual control, it is also suitable for use by mounting pneumatic actuator and electric actuator.
