Premium Radiator Valves & Heating Accessories

Ensure a flawless, leak-free installation and optimal thermal control with the comprehensive collection of radiator valves and accessories at Simco Direct. While radiators provide the warmth, the valves and fittings are the crucial components that control water flow, regulate temperatures, and provide the perfect aesthetic finish to your home heating project.

Whether you are fitting a modern designer vertical radiator, a traditional column radiator, or replacing standard panel units, our high-quality accessories deliver the reliability and style your interior demands.

Essential Radiator Valves for Every Installation

Selecting the correct valve depends entirely on how your pipework is configured and how you want to manage your room temperature:

  • Angled Radiator Valves: The most popular choice for UK homes. Designed for installations where pipework comes out of the wall or up through the floor and connects directly to the side inlets of the radiator at a 90-degree angle.
  • Straight Radiator Valves: Engineered for horizontal pipe runs where the pipework runs flat along the floor or wall directly into the ends of the radiator without bending.
  • Corner Radiator Valves: Ideal for tight spaces or minimalist designs where pipework comes straight out of the wall and you want the valve body neatly tucked away, keeping lines clean.
  • Thermostatic Radiator Valves (TRVs): Equipped with internal wax or liquid sensors that automatically adjust water flow based on ambient room temperature, helping you save energy and reduce heating bills.
  • Manual Valves: Traditional turn-handle valves that give you direct, manual control over water flow without automatic temperature sensing.

Finishing Touches: Pipe Sleeves, Shrouds & Wall Stays

Complete your installation with professional-grade finishing accessories that elevate the look of your heating system:

  • Pipe Sleeves & Collar Kits: Snap over exposed copper or plastic pipes to match your radiator or valve finish, hiding unsightly pipework.
  • Matching Lockshield Caps: Protect and conceal the balancing side of your radiator setup for a uniform aesthetic.
  • Wall Stays & Support Feet: Essential for securing heavy vertical or multi-column radiators safely to the wall or supporting their weight off the floor.

FAQs

  • What is the difference between angled and straight radiator valves?

    The difference depends on the direction of your pipework:

    • Angled valves are used when pipes emerge from the wall or floor and meet the radiator at a 90-degree angle.
    • Straight valves are used when pipework runs horizontally along the floor or wall straight into the ends of the radiator.
  • Do I need a Thermostatic Radiator Valve (TRV)?

    Yes, TRVs are highly recommended and are often required by UK building regulations for habitable rooms. They allow you to set a desired temperature for individual rooms, automatically turning the radiator down when the room is warm enough to maximize energy efficiency.

  • What is a lockshield valve and what does it do?

    A lockshield valve is the valve on the opposite side of the radiator from your control valve (TRV or manual). It is capped off and used by heating engineers to "balance" your central heating system—meaning it regulates the flow of water so that all radiators heat up evenly across your home.

  • Are radiator valve connections a universal size in the UK?

    Most standard UK domestic radiators and valves feature standard 1/2-inch BSP (British Standard Pipe) male threads connecting to the radiator, and 15mm compression fittings for standard UK copper or plastic pipework. Always double-check your pipe diameter before ordering.

  • What are pipe sleeves and collars used for?

    Pipe sleeves and matching collars are decorative covers placed over exposed copper or plastic pipes running from the floor or wall to the radiator valves. They hide discolored or mismatched pipes, creating a clean, integrated, and high-end aesthetic finish.
