Characteristics

Wafer type connection with minimal space occupation. The valve body does not have an independent flange and is directly clamped between two pipeline flanges using double headed bolts. Its axial length is only 1/2~1/3 of that of a flange butterfly valve, and its radial size is compact, reducing weight by 30%~60%. It is particularly suitable for narrow installation environments such as dense pipelines, equipment rooms, and underground pipelines, while reducing labor/equipment costs for handling and installation.

Wafer Butterfly Valve Characteristics

Key Advantages

  • 1 Butterfly valves have the characteristics of simple structure, small volume, light weight, low material consumption, small installation size, fast switch, 90° reciprocating rotation, and small driving torque.
  • 2 Butterfly valves can transport mud and accumulate the least amount of liquid at the pipeline outlet. Under low pressure, good sealing and regulation performance can be achieved.
  • 3 The streamlined design of the butterfly plate reduces fluid resistance loss, making it an energy-saving product.
  • 4 The valve stem is a through stem structure that has undergone quenching and tempering treatment, ensuring excellent mechanical properties and corrosion resistance.
  • 5 Various connection methods include flange connection, clamp connection, butt welding connection, and lug clamp connection.
  • 6 Multiple driving forms: manual, worm gear transmission, electric, pneumatic, hydraulic, and electro-hydraulic linkage.

Frequently Asked Questions
Q: What is a wafer butterfly valve and how does it differ from a flange butterfly valve?
A wafer butterfly valve is clamped directly between two pipeline flanges using double-headed bolts, without an independent flange on the valve body. Compared to a flange butterfly valve, it has an axial length of only 1/2 to 1/3 and a weight reduction of 30%–60%.
Q: What sealing materials are used in this wafer butterfly valve?
The sealing surface uses elastic materials including nitrile rubber (NBR), ethylene propylene diene monomer (EPDM), and fluororubber (FKM), reaching ANSI B16.104 Class VI leakage levels.
Q: What is the operating temperature range of this butterfly valve?
This wafer butterfly valve is designed for a temperature range of -20°C to 120°C, suitable for most industrial and commercial pipeline applications.
Q: What actuation and connection options are available?
It supports flange, clamp, butt welding, and lug clamp connections. Actuation includes manual, worm gear, electric, pneumatic, and hydraulic mechanisms.
Q: What standard does this wafer butterfly valve comply with?
This valve is manufactured in compliance with the EN593 standard for industrial butterfly valves, utilizing high-quality investment casting workmanship.
Q: How is the valve packaged for export?
The valve is packaged in a standard export wooden case designed to withstand long-distance shipping, providing robust protection against impact and moisture.
