Ball valve for water DN 40 WKP 2a 1.6 - 4.0 MPa APA04010040160

Application and Scope of Work in Industrial Installations

This full-bore flanged ball valve DN 40 is designed for operation in demanding environments, such as district heating networks, air conditioning systems, water supply installations, and other industrial circuits. The device is suitable for conveying media classified as Group 2 according to Directive 97/23/EC, including water, oils, and other fluids that do not react chemically with carbon steel. This ensures safe and durable installation in typical heating and process systems.

It is worth noting the pressure flexibility of this model – it operates within a range of 1.6 MPa to 4.0 MPa (from 16 to 40 bar), allowing its use in installations with varying working pressures. The operating temperature range extends from -20°C to +200°C, making it a universal component for both cold water systems and high-temperature heating circuits.

Construction, Installation, and Control Options

A key feature of this valve is its full-bore design, which minimizes flow resistance and prevents the accumulation of contaminants inside the body. Flanged connections facilitate quick installation in existing pipeline networks without the need for additional reducers or threaded transitions. The device is standardly equipped with a manual operating handle, enabling intuitive manual control.

For installers working in hard-to-reach locations or requiring automation, the manufacturer offers the possibility to adapt the valve:

• Installation of a worm gear reducer – facilitates operation under high torque conditions or in inaccessible locations.
• Preparation for actuator mounting – enables integration with building automation systems (electric or pneumatic actuators).

Flange connection dimensions comply with industrial standards, and the construction is based on a solid ball sealed with special rings (O-rings) and springs ensuring tightness even at high pressures.

Compliance with Standards and Key Operational Parameters

The valve meets rigorous requirements regarding tightness and durability, confirmed by the ŚZSJ Certificate No. 2/17 and Declaration of Conformity No. 32/AP. Tests were conducted in accordance with standard PN-EN 12266-1, guaranteeing reliable performance under industrial conditions. The manufacturer provides a 2-year warranty for this product, which is standard for high-class fittings intended for continuous operation.

For this DN 40 nominal diameter model, key operational values include a maximum working pressure of 40 bar (4.0 MPa) and an operating temperature range from -20°C up to +200°C. This combination of parameters makes the valve suitable not only for standard water installations but also for more demanding industrial and district heating applications where environmental conditions vary. Thanks to the combination of a wide pressure and temperature range with full-bore flow, this model represents an optimal solution where reliable shut-off and minimization of pressure drop in the system are critical. It is a component that requires minimal maintenance due to its simple ball construction and high-quality seals.
