5. To get off axis core, diaphragm, piston, do not damage the diaphragm. 2. The piping on the main valve cover joint screw loosening, internal pressure release valve. 7. If found diaphragm or ring has destroyed, please loose the nut on the axis core, get to decompose the diaphragm or circle, after extracting anew with a new diaphragm or ring. 。 Q: parsing hydrodynamic stem valve maintenance and protection of answer: hydrodynamic stem valves, valve is pressure stem hydrodynamic stem valve consists of a main valve and set the catheter, pilot valve, needle valve, ball valve and pressure gauge, etc. Hydrodynamic stem valve is a kind of water is used since embellish body, no other oil lubricating oil, in case of the main valve in the zero damage to Marine valve device, please follow the below list ordering disassembly. 6. After the above items to extract, seizing type, diaphragm and a. circle is destroyed; Such as shape do not bad points to contend for its inner parts. ( Note: the average consume loss elimination in the valve products for diaphragm and ring, other inner parts damaged little) 1. The main valve before and after the first side gate valve closed. 9. According to the reverse is down the order will change the zero combination device installed after the main valve, pay attention to the valve which permits jam phenomenon. 4. Take the cover and spring. 8. Carefully examines the main valve seat, shaft core inner whether have damage, if there are other debris inside the main Industrial Valves to sort out it outright. 3. Will take off, all the screw cover stem line indispensable in the brass nut. On the basis of using the target, function and place different can morph into remote sensing floating ball valve, reduce the pressure valve, slow close check valve, flow stem valve, relief valve, water power electric stem valves, water pumps, stem valves, etc. Hydrodynamic stem valve before to install the filter device, and should be easy to drain. Notes to the order: The national standard) A, A: B: product name, model, nominal size medium and temperature, pressure range C: whether there is attachment, delivery time, and special requirements so that we can correct selection for you.
