The Pegler Bulldog II Angled TRV and Lock Shield Pack is designed for homeowners and heating professionals seeking precise climate control in both residential and commercial settings. Its primary benefit is a highly accurate wax-filled sensor that enables temperature regulation from 11 to 29 degrees Celsius, ensuring energy efficiency and comfort. However, users should note that the angled configuration requires specific pipe positioning and may not be compatible with all straight-entry radiator configurations without additional fittings.

Yes, this is a comprehensive pack that includes both the thermostatic radiator valve (TRV) and the corresponding lockshield valve.
Yes, the Bulldog II is specifically designed to meet the demands of both domestic and commercial heating environments.
The wax-filled sensor provides precise, repeatable temperature control by expanding or contracting in response to room temperature changes.
The valve is rated for systems operating up to 10 bar of pressure.
Check if the internal valve pin is stuck; remove the thermal head and gently press the pin to ensure it moves freely.
Verify that the thermal head is properly tightened onto the valve body and that the sensor is not being blocked by curtains or furniture.
Ensure the system is drained before beginning installation of the 15mm angled valves. The pack is designed for standard 15mm pipework common in most UK and European radiator systems. During installation, ensure the valve body is oriented correctly to allow the thermal head to sense room air temperature without obstruction from curtains or radiator covers. For maintenance, simply wipe the chrome exterior with a damp cloth; avoid abrasive chemicals that might damage the polished finish. Periodically check the valve movement by turning it through its full range to ensure the internal mechanism remains free-moving.
