1″ Female Swivel x 28mm Extended Lever Ball Valve
The 1″ Female Swivel x 28mm Extended Lever Ball Valve provides convenient isolation around an air source heat pump installation.
It combines a 1″ female swivel connection with a 28mm pipe connection. Therefore, installers can create a practical transition between heat pump components and 28mm heating pipework.
The extended operating stem also makes the valve particularly useful around insulated external pipework.
Designed for Air Source Heat Pumps
Air source heat pump installations often need isolation points close to the outdoor unit.
This allows an engineer to isolate sections of pipework during servicing, maintenance or component replacement.
The extended design makes access easier after insulation has been fitted. As a result, the installer does not need to remove large sections of insulation simply to operate the valve.
Comparable heat pump valves use this arrangement between the heat pump, flexible hoses, antifreeze valves and the wider heating system.
1″ Female Swivel Connection
The female swivel connection provides greater flexibility during installation.
Instead of rotating the entire valve or adjoining component, the swivel connection helps the installer make the joint more easily.
This can prove especially useful near an outdoor heat pump where installation space may be limited.
It can also make future servicing and replacement work easier.
28mm Pipe Connection
The opposite side connects to compatible 28mm heating pipework.
Therefore, the valve works well on many domestic air source heat pump systems that use 28mm primary pipework.
Always check the existing pipe size before ordering a replacement.
You should also confirm the connection arrangement on the heat pump, hose or adjoining valve.
Extended Lever for Insulated Pipework
External ASHP pipework needs effective insulation to reduce heat loss and protect the system.
Standard valve handles can become difficult to access once thick insulation surrounds the pipework.
An extended valve stem helps solve this problem. The operating point remains accessible while insulation surrounds the valve body and adjoining pipe.
Therefore, engineers can isolate the circuit without unnecessarily disturbing the insulation.
Ideal for ASHP Repairs and Replacement
As the number of air source heat pumps installed across the UK increases, more systems will require servicing and replacement components.
Isolation valves may eventually need replacing because of:
- Damage
- Leakage
- Seized operation
- System alterations
- Heat pump replacement
- Pipework upgrades
- Routine refurbishment
This valve provides a useful replacement option where the existing system uses the same 1″ female swivel and 28mm connection arrangement.
However, always compare the existing component before ordering.
Flow and Return Isolation
Heat pump installations commonly require isolation on both the flow and return pipework.
This allows engineers to isolate the outdoor section of the system when carrying out maintenance.
It can also simplify the replacement of valves, hoses and other ASHP components.
Always follow the heat pump manufacturer’s hydraulic and servicing requirements.
Works Alongside ASHP Protection Components
A heat pump installation often includes several valves and protective components.
For example, a typical external pipe arrangement may include:
- Isolation valves
- Antifreeze valves
- Flow balancing valves
- Fill and flush points
- Filters
- Flexible heat pump hoses
- Pipe insulation
Kudos Trading already stocks several of these products for professional heat pump installers.
Our 28mm Ball Valve with 500 Micron Filter provides isolation together with debris protection. The product is currently held in stock on the Kudos website.
We also stock several heat pump antifreeze valves. These include 1″ swivel and 28mm options for suitable monobloc installations.

Choosing the Correct Replacement Valve
First, check the existing connection at the heat pump or adjoining component.
Next, confirm that the heating pipework uses a 28mm connection.
Also, check the available installation space and insulation thickness.
Finally, compare the replacement valve with the original system specification.
Do not choose a heat pump replacement part from appearance alone. Connection size and system requirements must also match.

Frequently Asked Questions
What Is an Extended Heat Pump Ball Valve?
It is an isolation valve with an extended operating stem.
The extra length keeps the operating point accessible after insulation surrounds the pipe and valve body.
Why Does This Valve Have a Female Swivel?
The swivel makes installation easier around fixed heat pump components.
Therefore, installers can tighten the connection without rotating the entire valve or adjoining equipment.
What Pipe Size Does This Valve Connect To?
This version connects to 28mm pipework on one side.
The other connection is a 1″ female swivel.
Is This Suitable for an Air Source Heat Pump?
Yes. This connection style is designed for compatible heat pump installations.
However, always confirm the heat pump and pipework requirements before ordering.
Can I Use It on the Flow or Return?
Yes, where the system design permits.
Heat pump installations often use isolation valves on both the flow and return.
Why Is the Extended Stem Useful?
ASHP pipework normally requires insulation.
The extended stem allows the valve to remain accessible without removing the insulation every time an engineer needs to operate it.
Can I Use This as a Replacement Valve?
Yes, provided the connection sizes and system specification match.
Check the existing valve before ordering. Also, confirm any manufacturer-specific requirements.
Should I Install Antifreeze Valves as Well?
Many monobloc heat pump installations use mechanical antifreeze valves to provide additional frost protection.
However, the exact frost protection arrangement depends on the heat pump manufacturer and system design.
