ZLF self operated flow balance valve (without lock)

Product model:Self operated flow balance valve (without lock)
Product features:ZLF self balancing valve is a kind of self control using the pressure change of the medium itself, so as to maintain the flow through the controlled system constant flow valve, suitable for heating and air conditioning systems and other non corrosive medium flow control. Once the test is adjusted before operation, the system flow can be automatically kept constant in the preset setting value

A,ZLFSelf operated flow balance valve(Without lock)Product overview

ZLFSelf balancing valve is a kind of self control using the pressure change of the medium itself, so as to maintain the flow through the controlled system constant flow valve,ZLFSelf balancing valve has flow indication, which can be adjusted online. It is suitable for flow control of non corrosive media such as heating and air conditioning system.ZLFSelf balancing valveBefore the disposable test regulation, can make the system automatically constant flow in the preset settings.ZLFSelf balancing valveThe flow regulation is accurate, the operation is simple, the operation is steady, the performance is reliable, and the service life is long.

ZL47-16 self operated flow control valve is a kind of automatic constant flow hydraulic balance valve. The flow can be set according to the demand and the flow through the valve is kept constant. It is applied to the central heating, central air conditioning and other water systems, so that the flow adjustment of the pipe network is completed at once, and the network adjustment work is simplified into a simple flow distribution. The flow redistribution work is avoided when the heat source is switched, and the hydraulic imbalance of the pipe network can be effectively solved.

Structure characteristics
Self operated flow control valve (ZL47) is to set the flow according to the controlled pipeline, and can lock the set state. Surplus pressure pipeline can be automatically eliminated, the branch line between the flow regulation do not interfere with each other, the direct flow of digital display, nominal pressure 1.6Mpa, the medium temperature of 0-120, the body made of grey cast iron, carbon steel, copper alloy forging, pieces of material with copper alloy and stainless steel.
Installation instructions
It should be installed according to the flow direction shown by the arrow of the valve body. It must not be installed in reverse direction. It can be installed vertically or horizontally on the pipe. Flow setting method: use special wrench, open the protective cover, rotate the stem, so that the calibration line to the corresponding value of the set flow. Another shutoff valve should be set up.
