Robinet à boisseau sphérique pour eau DN 100 WKP 2a 1,6 MPa APA10010016160

Application and Media

The valve is designed for systems conveying media that do not react with carbon steel — primarily water, oils, and air. It operates safely in district heating, air conditioning, water supply, and other industrial installations. Compliant with Directive 97/23/EC for Group 2 fluids, meaning it can be used in pressurized systems without additional restrictions.

Construction and Operation

This full-bore ball valve with flanged connections features a simple yet effective design: a floating ball with seals ensures tight shut-off, while the stem is sealed with an O-ring — a solution that minimizes leakage risk during cyclic operation. The valve is disassemblable, facilitating maintenance and seal replacement without the need to dismantle the entire assembly. The option to mount a worm gear operator or to connect to an actuator provides flexibility — allowing manual or automatic control depending on installation requirements.

Operating Conditions and Compliance

It operates at a maximum pressure of 1.6 MPa (16 bar), meeting standard requirements for most district heating and industrial networks. The temperature range is -30°C to +200°C, enabling use in both cooling systems and high-temperature steam circuits. The version with code APA10010016160 complies with PN-EN 12266-1 regarding tightness and strength testing of valves. The CE certificate confirms compliance with applicable EU regulations.

The valve weighs 19.7 kg — sufficiently heavy to ensure stability during flanged installation, yet within practical limits for transport and handling.
