Symax collarless butterfly valve with manual lever drive DN65 149G012332

SYLAX Flapper Valve – Reliable Flow Control

The SYLAX flapper valve with manual lever drive is a robust solution for flow regulation in water and industrial installations. The design allows for precise control, and the materials used guarantee long-lasting and trouble-free operation. Ideal for systems requiring manual flow control, where reliability and ease of use are important.

Construction and Application

The valve is designed for mounting on PN6/10/16 flanged connections with a nominal diameter of DN65 (2 1/2 inches). Made of GG25 cast iron, coated with an epoxy coating, it provides corrosion and mechanical damage resistance. A replaceable stainless steel AISI316 disc and EPDM lining guarantee tightness and compatibility with various media. A one-piece stainless steel shaft increases the durability and reliability of the drive mechanism.

• Flapper design minimizes pressure loss and facilitates medium flow.
• Lever drive enables quick and intuitive flow adjustment even in difficult conditions.
• Centering holes in the housing facilitate precise mounting and ensure installation stability.
• Replaceable sealing elements and disc allow for easy maintenance and adaptation of the valve to various applications.

Operating Parameters and Safety

The SYLAX valve is designed to operate at a maximum differential pressure of 16 bar and a medium temperature of up to 120°C. The EPDM rubber seal ensures high tightness in the temperature range of -10°C to +120°C. ANSI / FCI 70-2 (IEC 60534-4) – I tightness class confirms the high quality of workmanship and reliability of the device.

• Housing material: GG 25 (GJL-250) cast iron – provides mechanical strength and corrosion resistance.
• EPDM seal: Guarantees tightness over a wide range of temperatures and pressures.
• Maximum working pressure: 16 bar – allows use in installations with increased pressure.
• Maximum medium temperature: 120°C – allows operation with hot liquids and gases.
