The installation of the hydraulic control valve hydraulic control valve should be installed horizontally. When mounted horizontally, the cover should be upward. After the fire water system of the pressure reducing valve valve should have drainage facilities. Automatic sprinkler system should be reduced pressure, the pressure reducing valve should be set up before the alarm valve ( Along the flow direction) , with a single alarm valve set pressure reducing Industrial Valves, not equipment with a pressure reducing valve; With multiple alarm valve set pressure reducing valve, factory should use pressure reducing Industrial Valves. Used for hot water supply project of the pressure reducing valve, hot water operated pressure reducing valve should be adopted. Using the main mains cycle way ( A circular manner) The hot water supply project, pressure reducing valve set requirements shall be the same as the cold water engineering; By adopting the riser ( Full circulation way) The hot water supply project, pressure reducing valve should be set to prevent the destruction of the hot water circulation, each partition return pipe should balance the pressure point. Hydraulic control valve hydraulic control valve of the main valve to remove the main valve is a kind of water is used since embellish type body, do not need to add oil lubrication, in case of damage of main parts in the valve, please follow the instructions below to remove. ( Note: in general consumption in the valve damage product for diaphragm and ring, other internal components damage little) 1. The main valve before and after the first side gate valve closed. 2. The piping on the main Industrial Valves cover joint screw loosening, pressure release valve. 3. All the screws removed, including controlling necessary pipeline brass nut. 4. Take the cover and spring. 5. To get off axis core, diaphragm, piston, do not damage the diaphragm. 6. Remove the above things, diaphragm and examine whether the protection ring damage; If no damage do not again points to its internal parts. 7. If found that the diaphragm or ring was damaged, please loose the nut on the axis core, get to decompose the diaphragm or circle, comes out to replace the new diaphragm or ring. 8. To examine in detail the main valve internal seat, shaft core whether have damage, if there are other debris inside the main valve to clear it. 9. Combination is in reverse order will replace the parts after installed the main valve, no jam phenomenon should be the valve.
However, with the increased prevalence of double flanged gate valve, it has become far more affordable.
Deliver value to our customers by providing the most reliable and efficient products as flow control valve.
In the boundless Chinese market, there are a number of enterprises that provides resilient seated valve water gate valve of their own brand over the years, but few have won more support from customers on the international stage than Mech.
