Q:Can the check valve be used on the steam pipe?
The check valve can be used on the steam pipe, but only the right material.General steam pressure WCB, temperature and pressure with the then high chromium molybdenum steel. The inside of the valve should be taken into account, depending on the pressure difference.
Q:Method for mounting back check valve of pump

The center line of the flue and the center line of the reserved hole should be less than 1cm, the deviation of the centerline of the upper and lower flue is not greater than 1cm, and each flue must be guaranteed vertically and vertically.4, the installation of flue should each layer as bearing, bearing steel 2 root diameter over 14mm?.5. After the flue is installed, install the check valve hole at each flueFire type flue check valveFirst, stir the cement with a special glue, coat the edges of the check valve, and then install it at the opening of the check valve.6, the construction should be reserved at all levels of the hole, covered with a cover plate, to ensure safety in construction, to prevent construction waste fall into the flue.7, the flue is thin-walled components, in handling and installation should be gently handle, not to impact, not in the pipeline to pile other heavy objects and walking.8, the roof flue should be in the roof insulation layer, fire layer before construction. 9, the use of gas water heater exhaust system is strictly prohibited.
Q:Check valve authentication information
Consult the manufacturer for more information.Canadian, Registration, Number, CRN certificationMany of the Check-All valves have also been registered in Canada (0C3651.5R1C). Under some special conditions in Canada, the use of some products requires a Canadian registration code CRN. Check-All is registered in all provinces and territories of canada. CRN testing and labeling requirements are required at the time of ordering. If you need valves containing CRN, consult your manufacturer.Hygienic standard for Sanitary Standards3AThe Check-All 3SC Series Check Valves comply with 3A hygiene standards for milk and milk products, vacuum eliminator and check valves, and the standard number is 58-01. Among other requirements, the standard requires 32 radium processing, with precise groove angle and depth, all for sanitary purposes.
