Pressure reducing valves REDUFIX - Watts Industries

Pressure reducing valves
REDUFIX
• Compact, preset adjustable pressure reducing valve.
• Outlet pressure setting range : 1,5 to 5 bar.
• Corrosion preventing DZR brass body.
• Female 1/4” pressure gauge connection.
• Maintenance free.
• Ideal for protecting electric water storage heaters and household appliances.

PRESSURE REDUCING VALVE • REDUFIX
Use :
REDUFIX is an ideal pressure reducing valve for sanitary water systems.
REDUFIX is designed for protecting single appliance like water storage heaters
and household appliances.
It is directly fitted upstream of the appliance that you want to protect or to water
circuit inlets that you want to protect (kitchen, bathrooms, garden piping etc.).
Approvals :
Wras (UK), ACS (F).
Advantages :
• Compact
Takes up less space, easier to fit, It is at present the
more unobtrusive underneath water heaters.
• Ready to install
Factory preset,
You can change the setting from 1,5 to 5 bar.
• Any position
The REDUFIX can be fitted in any position.
• Robust
Once fitted you can forget it. The REDUFIX does not
require any special maintenance.
• Silent
The valve system design and types of seals used
ensure operation with no vibration and no banging
about.
• Specific discharge
Discharge is appropriate to isolated appliances like
washing machines or water heaters. It has a part in
better thermostatic mixer control and controlled water
consumption.
• Practical
Its Female 1/4” pressure gauge outlet is located on
the front and not under the valve.
• Tried and tested reliability
On the market for over 20 years, the REDUFIX is
made at Fressenneville in France in our production
unit ISO 9001 certified by BVQI.
Why 3 bar presetting
Because all features introduced by valve manufacturers
are measured to 3 bar*.
Too high a pressure over 3 bar would result in
accelerating water velocity in pipes with the risk
of:
• Creating water hammer,
• Washing off the grease on ceramic inserts making
head and lever movement harder,
• Causing water in electric water heaters to expand too
quickly causing the valve of the safety valve unit to
open prematurely leading to significant water
consumption.
So the REDUFIX is factory preset at 3 bar.
This safety guarantee has made REDUFIX a market
success for over 20 years.

• Loosening limestone deposits in pipes causing ceramic
inserts to break when taps are fitted with them,

Recommendations / installation :
- Rinse the upstream pipes carefully to remove oakum, teflon, weld spatter, grit etc., before fitting the REDUFIX.
- Fit the REDUFIX to the inlet of the water circuit that you want to protect (kitchen, bathrooms, garden piping etc.).
- The setting can be adjusted between 1,5 and 5 bar.
Screw or unscrew the setting screw on the top of the appliance with a screwdriver to raise or lower this setting.
After opening then closing a valve on the downstream circuit, check the pressure on the pressure gauge.
- You do not have to comply with any special position.
- The REDUFIX technical specifications do not change whichever operating plan is used.
- The hexagonal plug opposite the head can be taken off for blowing down or draining.
The REDUFIX requires no special maintenance, nonetheless we recommend that it is fitted in an accessible place.
