Butterfly installation techniques and how to use equipped with flange and bolts needed to regulate the flow, there are worm gear box control. Open and close the valve more frequently, Weifang steel valves, about two months time, the worm opens the lid to check whether the normal butter should maintain the right amount of butter. Check the connection site requires compression, which is to ensure filling of bees, but also to ensure a flexible stem rotation. BD343H flange butterfly hard seal insulation Features: 1, using three-dimensional eccentric structure, seat and disc almost no friction, with more closed more tight sealing function and wear compensating seals deputy. 2, the seal is soft and hard stacked metal sheets, valves, a metal seal and elastomeric seal the dual advantages. 3, sealing surface heap Stellite alloy, Shandong steel valves, seals wear resistance and long service life. 4, the use of different materials, both at low and high temperature, high pressure situation, both with excellent sealing performance, and can be made into two-way sealed type. 5, can provide a variety of transmission according to user requirements. 6, the electric valve can be manual or remote centralized control of the scene, and can meet the needs arts program-controlled computer. Testing and adjustment 1, the product either manual, pneumatic, hydraulic, electric various components in the factory are subject to stringent testing, the user when the sealing performance review should be uniformly fixed import and export sides, Shandong stainless steel valves, closed Singles valve on the inlet side pressure on the outlet side to observe whether the leakage phenomenon, in the pipeline before the strength test, you should open the disc plate to prevent damage to the seal pair. 2, despite the strict inspection and test, but there are also individual products in transit automatic screw deflection, need to re-adjust, pneumatic, hydraulic, etc. before the product shipped, please read the complete drive Manual 3, (electric valve) Factory When you have control enabled institutions close stroke adjusted. To prevent the power-on is the wrong direction, the user after the first powered on, the first being opened manually to a half-open position, in accordance with the electric switch plate check indicates the direction of the valve closing direction can be consistent.
