Product introduction

F/F-08 series cast iron valves are equipped with electronic drive control devices to regulate the flow of cold and hot water. The liquid control of central air conditioning, heating, water treatment, industrial processing industries and other systems is widely used.

Features

● Flow characteristic curve: straight line / equal percentage
● Flow error ≤ 5%
● Working temperature: 0~150°C

product advantages

● Stable: The flow of the end device is not affected by system pressure fluctuations, and the flow changes do not interfere with each other.
● Energy saving: 6~20% energy saving compared with traditional systems
● Efficient: greatly shortens the debugging time, and the system runs with high efficiency.
● Comfort: control temperature accuracy is more comfortable, more comfortable than traditional variable flow system

Material and life

● Valve body: high quality gray cast iron.
● Spring: stainless steel
● Life expectancy: more than ten years
● Internal parts: brass, stainless steel
● Diaphragm: EPDM

Installation and maintenance

● Under the stem, the valve is closed.
● Before installing the valve, ensure that the pipe is clean and there are no other oxides such as scales, metal sheets and the like left during welding.
● The pipe must be concentric when connected to the valve body; it is not subject to vibration, and the direction of water flow should be consistent with the upper surface of the valve body.
● There should be no pressure on the water system when maintaining the valve
