This model is a durable valve designed for use in industrial liquid and gas applications. It offers high reliability and long service life, especially in automation systems and fluid control circuits.

Type: 2/2 Way

"2/2 way" valves have two ports and two positions. They are typically used for on/off control, allowing or stopping the flow of liquids or gases in a single direction. This type is among the most commonly used control valves in the industry.

Connection Size: 1/2" – 4" Threaded / BSPP (G)

The valve is available in sizes ranging from 1/2" to 4", with BSPP (British Standard Pipe Parallel) threaded connections. BSPP threads are widely used in Europe and Turkey and typically require a sealing washer or gasket for tight sealing.

Valve Body: Nickel-Plated Brass

Brass is a durable and easily machinable material with natural corrosion resistance. The additional nickel plating provides enhanced protection, especially in applications with frequent fluid contact, preventing oxidation of the surface and offering a smooth, clean finish.

Operating Temperature: -20°C to +130°C

This temperature range allows the valve to function reliably in both cold and hot environments. It can withstand freezing conditions down to -20°C and is suitable for use with hot fluids or steam up to +130°C.

Operating Pressure:

• For sizes 1/2" to 2": PN40 (up to 40 bar operating pressure)

• For sizes 2 1/2" to 3": PN25 (up to 25 bar operating pressure)

"PN" (Pressure Nominal) indicates the maximum pressure the valve can handle continuously. 1 bar ≈ 14.5 psi. These valves are suitable for high-pressure systems.

Sealing Material: PTFE

PTFE (Polytetrafluoroethylene), commercially known as Teflon, is a widely used and high-performance sealing material. Key features include:

• Excellent chemical resistance (unaffected by acids, bases, etc.)

• Very low coefficient of friction (no need for lubrication)

• High thermal resistance

• Complete resistance to moisture and water leakage

• Non-hardening and non-stick over time

Thanks to these properties, PTFE seals provide long-lasting, leak-free performance even under harsh operating conditions.
