Polypipe Stainless Steel UFH Isolation Valves 1" — Pair | Manifold Supply Isolation | UFH165
Polypipe Stainless Steel UFH Isolation Valves 1" — Pair | Manifold Supply Isolation | UFH165
UFH165 Pair (Flow & Return) 1" BSP — Stainless Steel
The Polypipe UFH165 Stainless Steel Isolation Valves are supplied as a pair — one valve for the flow connection and one for the return — and are used to connect the Polypipe stainless steel manifold assembly to the UFHSPP1 manifold control pack (pump and mixing valve unit) and to the boiler supply pipework via UFH170 adaptors. The isolation valves allow the manifold and control pack to be isolated from the system pipework for servicing, without the need to drain the entire underfloor heating system. Stainless steel construction matches the Polypipe stainless steel manifold range and provides long-term corrosion resistance in heating system environments. The UFH165 valves are sold separately from the manifold and the UFHSPP1 control pack and must be specified alongside both.
Role in the Manifold Assembly
The isolation valves sit between the stainless steel manifold body and the UFHSPP1 control pack. Their position in the assembly means that, when both UFH165 valves are closed, the manifold circuits and control pack can be fully isolated from the boiler pipework — allowing the pump, mixing valve, or manifold components to be removed, serviced, or replaced without shutting down the boiler or draining the wider heating system.
Key Features
- Stainless steel construction — matches the Polypipe stainless steel manifold range in both material and appearance; long-lasting corrosion resistance in closed heating system water
- 1" BSP connections — standard 1" BSP thread compatible with the Polypipe stainless steel manifold end connections and the UFHSPP1 control pack inlet/outlet connections; UFH170 adaptors (sold separately) transition to 22mm compression for boiler pipework
- Supplied as a pair — one pack contains both flow and return valves, providing complete supply-end isolation of the manifold assembly in a single order
- Ball valve mechanism — quarter-turn isolation for fast, positive shut-off; provides clear open/closed indication for safe system isolation during maintenance
- System isolation without full drain-down — closing both UFH165 valves isolates the control pack and manifold from the boiler circuit, enabling work on the control pack or manifold without emptying the heating system
- Required for all stainless steel manifold installations — isolation valves are supplied separately from the manifold and must be ordered alongside the manifold and UFHSPP1 control pack to complete a functional assembly

⚠️ Sold Separately — Must Be Specified
The UFH165 isolation valves are not included with the stainless steel manifold or the UFHSPP1 control pack. They must be ordered as a separate line item. A complete stainless steel manifold connection assembly requires: stainless steel manifold (PB127xx or UFH127xxEC) + UFH165 isolation valves + UFHSPP1 control pack + UFH170 adaptors. Missing any one of these four components will leave the assembly incomplete.
Frequently Asked Questions
What is the difference between UFH165 and UFH164?
Both are isolation valve pairs for Polypipe stainless steel manifold assemblies. The UFH164 is an earlier product code — the UFH165 is the current standard isolation valve pair for the stainless steel manifold range. If in doubt about compatibility with your manifold, consult the Polypipe product documentation or contact Polypipe technical support. In most current installations, UFH165 is the correct specification.
Can I use these valves with a plastic Polypipe manifold?
No. The UFH165 stainless steel isolation valves are sized and threaded for the 1" BSP connections on the Polypipe stainless steel manifold range. The Polypipe plastic manifold range uses different connection sizes and fittings — use the appropriate ancillaries specified for the plastic manifold system.
