Ball valve water DN 100 WK 2a 2.5 MPa APA10010025000

Application in Industrial and District Heating Installations

This flanged ball valve with nominal diameter DN 100 and pressure rating 2.5 MPa (25 bar) is designed for operation under demanding conditions in district heating networks, air conditioning systems, and water supply installations. Its construction enables safe control of media flow such as water, oils, or other fluids that do not chemically react with carbon steel. This is crucial for maintaining tightness and durability of the system over long-term operation. The device complies with Directive 97/23/EC for Group 2 fluids, meaning it can be used where high reliability is required when handling environmentally non-hazardous media that require precise shut-off.

Construction and Operating Conditions

The main component of this valve is a ball made of corrosion-resistant materials, ensuring minimal flow resistance and easy operation even at large diameters. The flanged mounting connection facilitates integration with existing pipeline infrastructure, eliminating the need for additional reducing fittings or direct welding. The valve is adapted to a wide temperature range – from -20°C to +200°C – making it a universal solution for both cold technological water and hot heating media. The maximum allowable working pressure (PS) is 25 bar in the 2.5 MPa version, although this series also offers variants up to 40 bar depending on the specific model.

For installers, the ability to adapt the operating method is important: the valve is standardly equipped with a simple "butterfly" type handle, allowing quick opening or closing (90 degrees). In cases of difficult access or the need for further remote control, there is an option to mount a worm gear reducer or prepare the body for such a reducer. The entire assembly undergoes rigorous tightness tests in accordance with standard PN-EN 12266-1, guaranteeing no leaks at the ball-seal interface or at flanged connections.

Practical Aspects of Operation and Installation

By choosing this ball valve model, you gain certainty of operation in high-flow systems without the risk of sudden failures caused by pressure or thermal overload. The device features high resistance to working pressure up to 25 bar (in the 2.5 MPa version), allowing its use in main distribution circuits of district heating networks. This eliminates concerns about sudden pressure spikes typical of such installations. The wide temperature range from -20°C to +200°C covers most standard industrial and municipal applications, ensuring trouble-free operation both in summer and winter.

Installation versatility results from the use of flanges – they allow quick disassembly and replacement without the need to cut pipes; the optional provision for a gear reducer increases project flexibility for future system expansion. Material compatibility is based on carbon steel, which is ideal for water and non-aggressive oils; however, its use with acids or strong alkalis should be avoided without additional protective coating. The product is covered by a two-year manufacturer warranty from IDMAR and complies with European standards regarding the safety of pressure equipment, which is important for public investment acceptances.

It is worth remembering that when installing valves with nominal diameter DN 100, appropriate pipeline supports should be provided to avoid excessive mechanical loading of the flanges during operation under pressure. Thanks to the simple ball construction, opening and closing time is minimal, facilitating rapid response to system changes or emergency situations. For comparison purposes, it is worth adding that this series includes models with diameters from DN 15 up to DN 200, and for size DN 100, versions with working pressure of both 16 bar (1.6 MPa) and higher – 25 bar (2.5 MPa) – are available, allowing precise adaptation of the device to the specifics of a given installation without the need for expensive pressure reducing equipment.
