CONTROL VALVES
Performance, Design & Service
The "Phoenix MFC" is a direct sealing diaphragm valve which consists of only three main parts: body, bonnet, and diaphragm.
The only moving component is the diaphragm which can operate in any of the following modes:
Closure - with drip tight shut off.
Full Open - free flow passage.
Modulating - restricting flow as dictated by the pressure in the control chamber.
Features
1. Hydrodynamic design with superior hydraulic performance giving low energy losses at high flow-rates.
2. Drip tight closure down to atmospheric pressure.
3. Easy in-line maintenance. One spare part accessible by removal of the bonnet. No special tools required.
4. The diaphragm, being the one free moving part, ensures smooth frictionless and fault free operation with low hystresis.
5. A locked in diaphragm, bolted between bonnet/body flange, prevents dislodgement in the event of extreme or back pressure, is unaffected by pipe stresses.
6. Simple sturdy construction with no crevices or contours, coated internally and externally prevents corrosion.
7. The natural tendency for the moulded diaphragm is to close automatically when the line pressure drops to about 0.5 kg/cm2 (7psi) which prevents line drainage.
8. Controllable opening and closing speeds prevents water hammer.
9. The internals are unaffected by precipitated deposits, such as dissolved minerals in water, which cause conventional valves to jam due to close-fitting parts.
10. No Sticking, even after prolonged periods, in the open or closed position.
11. Only the valve pilot system will activate the main valve and not external influences such as pressure surges
.
12. Internal ribs add strength to the contstruction and support the diaphragm preventing excessive deformation taking place.

SIMPLICITY
The "PHOENIX" MFC valve is designed ti withstand heavy duty conditions with the capability of providing a for flow control applications.
VERSATILITY
The "PHOENIX" MFC valve is ideal for industrial, mining, municipal, irrigation and fire protection applications as no shafts, seals or guiding bearings exist in the valve.
RELIABILITY
Our Valves
Control Functions
The " PHOENIX MFC " valve us designed to withstand heavy duty conditions with the capacity of providing a solution for flow control applications utilising a standard body with a variety of pilot configurations that can achieve a wide range of unctions such as:
MC MANUAL
On/off either locally or remote.
Speed control available on open/close cycle. (optional on all valves)
ES - ELECTRIC SOLENOID
Opens and closes on electric commmand. Standard 3/2 way configuration solenoid.
Voltages 24 volt DC, 110 & 220 volt AC.
PR - PRESSURE REDUCING
Maintains accurate downstream pressure regardless of upstream pressure fluctuations. Reduction ratio of up to 3:1 achievable as standard.
QR - QUICK RELIEF
Opens fully to relieve excess pressure out of the system when pressure surge occurs.
Closes slowly when normal conditions resume.
NR - NON-RETURN
Closes when downstream pressure exceeds upstream, protecting the system from water hammer.
FM - FLOAT CONTROL (MODULATING TYPE)
Controls liquid levels of tanks and reservoirs. The valve closes gradually when the preset level approaches.
FD - FLOAT CONTROL (DIFFERENTIAL ON/OFF TYPE)
The valves closes when the water level reaches maximum and opens only at the preset minimum.
