A brief introduction:
J13W series Internal screw stop valve Sealed valves are mandatory, so the valve is closed, the valve must exert pressure to force the sealing surface does not leak. When the medium into the valve from the bottom of the valve, the operating force required to overcome the resistance, is the stem and the packing friction and pressure generated by the media thrust force than the valve off the valve opening force, so the diameter of the valve stem, otherwise it will bend the stem top of the fault. Threaded valve is open, the valve opening height, the nominal diameter of 25% ~ 30%, the flow has reached the maximum that the valve has reached the full open position. So the valve fully open position, the valve stroke should be determined.
Two, Internal screw stop valve The design and manufacturing standards:
1, design and manufacture: GB12233;
2, the length of the structure: GB12221;
3, thread size: GB/T15918.1-93;
4, inspection and test: GB/T13927;
Three, Internal screw stop valve The advantages of:
1, simple structure, manufacture and maintenance more convenient.
2, the working stroke is small, open and close a short time.
3, good sealing, the sealing surface between the friction force is small, longer life.
Four, Materials for main parts the material of main parts

Five, Internal screw stop valve The main performance specifications Chief property and specifieation

Six, the main external and connecting dimensions Main external and connecting dimensions (mm)

Seven, design of ordering and selection of notes:
1, the product name and model of the products of the nominal diameter of pressure material by the use of the medium temperature and products with the attachment so that we provide you the correct selection.
2, if you have special request, please specify when ordering products in.
3, if the unit has been selected by the design model, please press the model directly to our sales department order.
4, the occasion is very important when using more complex or the environment when you try to provide design drawings.
Eight, customer service service commitment:
