Damper Valve
Product Advantages
Craftsmanship Ultra-high standard core technology
product composition
One-piece cast valve body The face-to-face dimensions of the one-piece cast valve body comply with ISO5752, ASME B16.10 and API609 requirements. Compared with other valve types, assembly is simpler and more flexible.
Top connection bracket The top connection bracket adopts ISO5211 standard flange and can be directly connected to various actuators.
Elastic metal sealing ring The elastic metal sealing ring is installed on the valve plate, and the sealing ring retainer is used to press it against the valve plate, which not only ensures the sealing ring is fixed, but also ensures a certain elastic deformation. The sealing ring is positioned by locating pins on its edge, making replacement of the sealing ring easier. The thickened design seal ring retainer is equipped with multiple hexagon socket bolts to compress the seal ring to ensure that the strength of the entire valve plate is more reliable.
Anti-blowout stem The standard outer-block anti-blowout design prevents the valve stem from blowing out and improves the safety of the valve.
Stem packing seal The valve stem packing seal can flexibly adopt a variety of structural forms according to the different working conditions of the media used by the valve. The packing design can meet the low emission requirements. The sealing form has passed the ISO 15848:1Class BH test and AP622 verification, including the flushing device and packing detection device for the packing and bearing. Diffusion leak detection meets the most stringent EPA and TALuft requirements
Metal seal valve seat The metal-sealed valve seat is cladded with Stellite alloy to ensure the durability of the valve in various applications including high temperatures and unclean conditions. Stellite alloy overlay seats are standard on all sizes.
High cycle thrust bearings The high-cycle thrust bearing device firmly presses a high-hardness thrust washer onto the shaft to form a central sliding washer, thereby extending service life.
Stem bearing The long bearing adopts surface hardening treatment to reduce valve stem friction and reduce torque. Suitable for dirty media or polymer working conditions, the bearing protection ring can provide excellent protection for the bearing and extend its life.
Product Quality Inspection Before Leaving The Factory
1. Inspect the products produced on the electric actuator production line every day, 100% inspection. First, open the indicator cover and check whether the wiring is beautiful, whether the limit cams in the opening and closing directions are fully raised, and whether the pointer position is consistent with the actual position of the actuator. , whether the screws inside are tightened, check whether the back cover is correct, and check whether there is paint peeling on the appearance of the electric actuator. Dirt, manual wrench, waterproof connector, manual dust plug, sight glass, and sight glass gland are all installed. After everything is correct, use a laser marking machine to mark the product number on the back of the electric actuator. The product number should include the date of the day, and finally put the foam into storage.
2. Inspection of complete sets of valves: After the valve assembly line operator completes the debugging, he will take the production order to the quality inspector, and the quality inspector will check the production order and products one by one (inspection items: valve quantity, diameter, material, connection Method. Whether the pressure is consistent with the production order, whether the voltage, control type, connection method of the electric actuator, whether it is an explosion-proof product, and whether it is consistent with the production order, whether the screws of the valve and electric actuator are tightened, whether there are any missing ones)
3. Inspection before packing: Check whether the product quantity, model, voltage, control method, and spare parts are consistent with the production order.
4. Inspection of random inspection products in the processing center: Once in the morning and afternoon every day, take the inspection item list to the processing center and randomly select a processed product from each machine. Find the operator of the processing center and ask him to measure one by one according to the inspection item list. , and keep records.
