Angle valve set for gas boilers Top-Therm Z-KIT-02-U — universal, includes filters, 2× 1/2" + 2× 3/4"

Top-Therm universal angle valve set Z-KIT-02-U is designed to provide shut-off and filtration for domestic gas boiler connections. The kit contains two 1/2" and two 3/4" angle valves with integrated filters, enabling isolation of inlet and outlet lines and protection against debris. The compact valves are suitable for new installations, replacement or routine maintenance of gas-fired boilers and allow convenient service without draining the entire system.

Advantages

The set combines inlet/outlet isolation and filtration in one compact solution, reducing installation time and simplifying service operations. Integrated filters capture particulates and protect boiler components from contamination. The inclusion of both 1/2" and 3/4" valve sizes covers common connection standards, making the kit adaptable to different boiler models. Valves are engineered for straightforward installation and reliable shut-off during repair or component replacement.

Suitable for

• Installation and replacement of domestic gas boilers
• Routine maintenance and servicing of boiler heat exchangers and pumps
• Situations requiring inlet/outlet isolation to avoid system drainage
• Protection of boiler components from debris and sediment

Key specifications

• Valve types: angled shut-off valves with integrated mesh filters
• Included sizes: two 1/2" valves and two 3/4" valves
• Functionality: inlet and outlet isolation with particle filtration
• Connection orientation: 90° angle design for compact piping layouts
• Typical application: domestic gas boiler water/gas circuit connections

How to use

Install the angle valves in the boiler inlet and outlet connections according to the boiler manufacturer’s piping instructions, matching the appropriate valve size to the connection thread. Tighten connections with appropriate tools and check for leaks at operating pressure. The integrated filters are accessible for inspection and cleaning; isolate the valve, relieve pressure locally and remove the filter screen for cleaning or replacement. Use the shut-off function to isolate the boiler when performing repairs, component replacement or system flushing.

Usage recommendations

For reliable operation inspect filters periodically and clean when flow is reduced or during scheduled maintenance. Ensure thread sealing materials and tightening torque follow boiler manufacturer guidance to maintain leak-free connections. When replacing valves, confirm compatibility with the boiler’s connection sizes and operating conditions.
