Ball valve water DN 150 WKN 2a 1.6 MPa APA15010016250

Application and Media

The valve operates in district heating, air conditioning, as well as water supply and industrial installations. It is designed for controlling the flow of water, oils, and other media that do not react chemically with carbon steel. It complies with the requirements of Directive 97/23/EC for Group 2 fluids — i.e., medium-risk media that are neither aggressive nor flammable.

Construction and Installation

Reduced-bore ball valve with flanged connection — a solution for circuits where full pipe diameter flow is not required, but solid and durable isolation is essential. The flange ensures tightness at high pressure (1.6 MPa), and the design allows installation in both vertical and horizontal systems without additional supports. Dimensions (285 x 285 mm) and weight (1 kg) indicate a compact yet robust construction — it requires no specialized tools for installation and remains securely in place even under dynamic hydraulic loads.

Advantages and Operating Conditions

• Carbon steel makes the valve resistant to mechanical damage — but only for neutral media; it is not suitable for acids, salts, or aggressive fluids.
• The flange eliminates the need for threading — enabling faster, tighter, and easier disassembly during maintenance.
• The reduced bore lowers weight and production costs — ideal where pressure drop is not critical.
• Operating pressure of 1.6 MPa is sufficient for most district heating and industrial networks — no risk of overload under normal operating conditions.
• Weight of 1 kg facilitates transport and manual installation — even in hard-to-reach locations.

There is no "magic" material or "modern" technology here — just a simple, proven valve made from what works: steel + flange + ball. It performs equally well in district heating networks as in industrial cooling systems — provided the media comply with the specified parameters.
