Tower Thermostatic Radiator Valve and Lockshield Pack with Drain-Off – TRVPACKDO
The Tower TRVPACKDO Thermostatic Radiator Valve and Lockshield Pack with Drain-Off is a practical and efficient solution for controlling radiator temperature while simplifying system maintenance. Designed for use in modern central heating systems, this pack combines accurate temperature regulation with enhanced servicing convenience.
The pack includes a TRV2 thermostatic radiator valve and an LS1DO manual lockshield valve with an integrated drain-off port, allowing precise control of heat output and easier system draining when required. Manufactured to comply with EN215 and BS7556 standards, the TRVPACKDO delivers reliable performance, durability, and improved energy efficiency.
TRV2 Thermostatic Radiator Valve
The TRV2 valve features a fully reversible body, allowing installation on either the flow or return, and supports both vertical and horizontal mounting to suit different pipework layouts. Temperature adjustment is controlled via a graduated scale, providing a working range of 7°C to 28°C, with an integrated frost protection setting below 7°C to help safeguard the heating system during colder conditions.
Constructed with a chrome-plated body and a liquid-filled sensor, the TRV ensures consistent and accurate temperature regulation. It connects via a standard 1/2″ BSP tail, compatible with 10–15mm fittings, and is rated for a maximum working pressure of 10 bar.
LS1DO Lockshield Valve with Drain-Off
The LS1DO lockshield valve offers dual functionality, allowing it to be used as either a lockshield or a wheel-head valve. Featuring bidirectional flow, it provides installation flexibility and is supplied with 15mm compression fittings and a 1/2″ BSP tailpiece. The valve includes a durable chrome finish with a white control knob and is supplied with a “witches hat” cap for lockshield applications.
An integrated drain-off port allows water to be removed directly from individual radiators, significantly reducing maintenance time. This feature is ideal for radiator replacement, system flushing, repairs, and balancing, eliminating the need to drain the entire heating system.
Application and Benefits
The TRVPACKDO is suitable for fully pumped central heating systems with up to 10 bar static pressure. The inclusion of a drain-off port improves servicing efficiency, supports accurate system balancing, and helps maintain optimal heat distribution throughout the property.
The Tower TRVPACKDO TRV and Lockshield Pack with Drain-Off combines temperature control, durability, and maintenance convenience, making it a reliable choice for both new installations and system upgrades.
