ITEM 420 - 2-way full-bore three piece stainless

Product catalog summary

General Features: The stainless steel ball valve, item 420, is a 2-way full-bore three-piece valve designed for easy maintenance. It supports various end connections including female threads, pocket welding, and butt welding. The valve operates within a temperature range of -20°C to +160°C and is suitable for fluids such as air, water, gas, petroleum, and aggressive media. The manual version lacks ISO 5211 top work, preventing actuator mounting.

On Request: Threaded NPT connections and seals made of PTFE with glass or carbon graphite are available. For other applications, contact the technical department.

Approvals: The valve is available in an ATEX version compliant with directive 94/9/EC.

Diagrams & Torque: The document includes pressure/temperature and flow-pressure loss diagrams. The Kv coefficient is defined for water at 15°C causing a 1 bar pressure loss. Breakaway torques vary by size and pressure, with a safety factor of 1.4 recommended.

Codes and Materials: The valve codes vary by size and execution (standard or ATEX). Materials include AISI 316 and 304 for various components, with PTFE used for seals.

Dimensions: Detailed dimensions are provided for sizes ranging from DN 10 (3/8”) to DN 50 (2”).

Drives: Options include double-acting and spring-return pneumatic actuators, with sizing based on a minimum supply pressure of 5.6 barg. Electric actuators are available on request.
