The static balance valve has a dual coneconstruction that limits the maximum stroke of the cone and thus limits theflow rate. At the same time, it also has the shut-off function. The staticbalance valve is equipped with a flow measurement connector and a differentialpressure valve pulse tube interface. Please follow the procedure described below
Limitflow:
Turn the turn-off handel counterclockwise to opent he valve. the dial indicator on the handle will point to 0, turn the handle3 clock wise to the desired set value ( for example, if the set value is 2.2, simply rotate the handle twice with the dial indicator point to 2.2). Turn off the mandrel set nut counterclockwise with the six-edge screwdriver (until it feels Cannot twist). Turn the handlecounterclockwise so that the scale pointer points to "0"
The valve is still open and locked in theposition it was just adjusted to meet flow requirements (2.2). To cancel thesetting, turn the mandrel set nut clockwise with the six-angle screwdriver(until it feels Cannot twist).
Note: At the same time, the scale pointerof the switch off handle must point to "0".
To read the set point, the valve should beclosed.
Measurementof flow and differential pressure
HTV03602 with two measuring joints (rectustype),
The pressure drop of the valve can bemeasured with measuring equipment. When the connector is connected to the quickconnector of the measuring equipment, the measuring connector can be opened byturning it half a turn counterclockwise with an 8mm open end wrench.
Install
The differential pressure valve must beinstalled in the return pipe, and the direction of water flow should beconsistent with the direction of the arrow on the valve body.
The static balancing valve must beinstalled in the water supply pipe, and the water flow direction should beconsistent with the arrow direction on the valve body.
The pulse tube must be installed betweenthe static balancing valve and the differential pressure valve. The pulse tubemust be flushed before installation.
Pressure test
Maximumtest pressure...................... 25bar
Whenperforming pressure tests on the system, it is necessary to ensure that thestatic pressure at both ends of the diaphragm is equal to prevent damage to thedifferential pressure controller. This means that the pulse tube must beconnected and all needle valves opened.
activate
Whenthe system starts - open the differential pressure balancing valve and theclosing valve on the matching valve - make sure that the static pressure onboth sides of the membrane is equal, or that the static pressure on the topside is higher than that on the bottom side.
Whenopening the differential pressure balancing valve and supporting valve (orstatic balancing valve) for water injection, open the supporting shut-off valve(or static balancing valve) first, and then open the differential pressurevalve to ensure that there is pressure on the top of the membrane.

Our brass valve is produced by forging, through forging the valve product strength is greater, no porosity, can effectively prevent the leakage of the valve body.
Our products are processed by precision CNC machine tools, with high machining accuracy up to 0.1 micron. We have machining centers to meet customers' requirements for products with high coaxiality
In our machining process, each size needs to be strictly tested. Workers will conduct a self-inspection of their products every 2 hours, and QC will conduct a workshop inspection every 2 hours to ensure that the size of products fully meets the requirements of the drawings
Our assembly shop USES the assembly line, the result of teamwork can guarantee the output of a large quantity of products.100% of the products on the production line need to pass the leak test. We use the pressure of 6-8bar to test each product. Only after passing the test can the products be packed into cartons.
