FLOAT SWITCHES & LEVEL CONTROLLERS

Application
While primarily designed for Ammonia, this control is also suitable for R-22 and other non-corrosive liquids that have a specific gravity of 0.5 or more. The controller is ideal for the control of the operating level of liquid in liquid refrigerant accumulators and separators. Although this is normally done with a solenoid valve, the controller can activate an alarm or a pump or similar device.

FKS 39 is an electro - mechanical float switch designed to provide a reliable, electro - mechanical response to liquid level changes.
The simple and basic design ensures long lifetime performance and reliable operation for many applications.
FKS 39 can control liquid level in vessels and accumulators or can be used as a low / high level safety alarm.

FEATURES :

• Based on float type 39F
• DIN , ANSI and FPT / NPT flanges
• The switch box can be placed in any position top of float housing for ease of installation.
• Adjustable liquid level differential switch point.
• Electro magnetic micro switch,mechanically activated.
• The complete switch box can easily be replaced without any interference with the refrigeration system.
• Switch box supplied with a DIN plug for easy installation and service.
• Flanges included.
• Float Switch are available in flame proof enclosure.

Application : These valves are for Ammonia duty. The MSVA are pilot operated valves whilst the MDSVA are direct operated solenoid valves. They are used in many applications such as cold stores, freezers, chilling applications etc.

Safe Working Pressure: 300psi

AVAILABLE IN SIZES:
15 mm / 20 mm / 25 mm / 32 mm and 40 mm

Valves are used for draining oil from systems containing refrigerant under pressure. The valve will close immediately upon release of the handle, thus protecting unnecessary refrigerant leak.

Application : Petroleum, Petrochemical, Chemical, Refrigeration, air-conditioning and engineering industries. Valves are compatible with Ammonia, CFQHCFC, Oil, Air, Chemicals, Gas, Acids, Alkalies etc. amongst many other media.

Refrigerants : Applicable to HCFC, HFC, R717(Ammonia) and R744 (CO2). For further information please see installation information for COFV
Temperature range : Standard version : -46 / +150°C
Pressure Range : The valve are designed for max. working pressure 40 bar g (580 psig)
