Delta TRV Range — Angled, Straight & Corner Thermostatic Valve Sets

Delta TRV Range: Angled · Straight · Corner Thermostatic Valve Sets

The Delta TRV Range delivers a neat combination of practical performance and designer finishes for modern radiator installations. Each set includes a wheel-head thermostatic valve and matching lockshield, with standard 15mm compression inlets and a ½" BSPT radiator coupler — specifications that suit the majority of UK radiators and typical pipework routes.

What makes Delta TRVs a practical choice

Delta valve sets are machined from brass and finished in multiple surface options (chrome, satin nickel, antique/antique copper, textured black, white and more). The choice of angled, straight or corner configurations lets you pair valves exactly to floor, rear or corner pipework without unsightly adaptors — reducing installation fiddles and improving the finished look.

How these TRVs save fuel and improve comfort

A thermostatic radiator valve measures room temperature and throttles hot-water flow through the radiator to hold the chosen setting. Using TRVs across rooms (plus a correctly sited room thermostat and programmer) avoids overheating unused spaces and lowers wasted energy — a practical step toward cutting annual heating costs in many UK homes.

Quick specification checklist (what to check before buying)

Orientation: Angle = floor entry; Straight = rear pipe entry; Corner = corner routing.
Connections: Typical Delta sets use 15mm compression inlet + ½" BSPT radiator coupler — measure your radiator tailpiece before ordering.
Finish & matching: Match valve finish to radiator trim and pipe sleeves for the cleanest visual result.
Warranty: Check the product page for warranty length — different Delta items list varying guarantees.

Practical installation pointers

For single-radiator swaps a confident DIYer can replace a valve if the central heating system is isolated and drained correctly. If the job affects the boiler, gas appliances or you’re not comfortable with isolating and refilling the system, use a Gas Safe registered engineer. After fitting: tighten compression fittings to avoid leaks, bleed the radiator thoroughly and set each TRV to the lowest number that maintains comfort in the room for best efficiency.

Common on-site fixes and what to keep in your kit

Keep spare olives, a small adjustable wrench, PTFE tape (for threads where applicable) and a radiator key handy. If a radiator has a cold top after fitting, bleed it first; persistent cold sections or leaks usually mean a seal/olive or valve body needs attention. If the TRV head sticks, remove it, check for scale/debris and consider replacing the thermostatic element rather than the whole valve if the body is sound.

Compliance & performance standard

Delta TRVs are intended for wet central heating installations; products sold for the UK market should meet the BS EN 215:2019 performance and testing requirements for thermostatic radiator valves — check the product documentation or datasheet if compliance certificates are required for a project specification.

Which finish suits which radiator style

• Chrome and satin nickel pair well with contemporary steel and column radiators.
• Antique finishes complement period-style radiators and traditional plumbing trim.
• Textured black and anthracite are excellent on industrial or matt-finish radiators.

Short buying checklist (at point of purchase)

Confirm orientation (angled/straight/corner).
Confirm inlet & outlet sizes (15mm compression / ½" BSPT are common).
Choose finish to match radiator and pipe sleeves.
Decide if you want wheel-head TRVs (cost-effective) or upgrade later to smart/electronic heads for zoning.
Check the return policy and warranty period on the product page.
