Features:

• Compact design, screw down lockshield.
• Designed solely for the use in an indirect, open vented or sealed water filled central heating and/or indirect hot water system.
• Glands can be removed without draining down.
• These valves are suitable for use with BS 2871 Part 1 table X copper tube and approved alternatives.
• The male tail pipe connections are BS21 taper threaded with an external square for easy fitting into the radiator.
• The lockshield valve is the valve on a radiator that is usually covered with a plastic cap.
• The term “lockshield” means that once adjusted, the valve is shielded with the plastic cap that prevents it being accidentally changed.
• The lockshield valve needs to be adjusted when 'balancing' radiators in the various rooms - Balancing means adjusting the flow of water through the radiators so they all heat up at eh same rate.
• If a radiator is takes too long to warm up, it needs more hot water flowing through it - If it gets hot quicker than others, then the flow through it needs restricting unless you want particular rooms to heat up faster than other.
