English
The micro resistance slow closing check valve is mainly suitable for water supply and drainage pipelines. It is installed at the outlet of the water pump to prevent medium backflow and eliminate destructive water hammer, and effectively reduce the pressure of valve closing water hammer, ensuring the safe operation of the pipeline network. It has the characteristics of light valve disc, large opening, good energy-saving effect, low fluid resistance, water hammer elimination mechanism design, stable sealing performance, wear resistance, long service life, stable operation, no vibration, and no noise.

1.The Bellow sealed globe check valve is a valve with two function ,which is globe and check valve. Connecting this valve’s stem and disc is designed to open structure . The stem can withstand the movement of the valve disc when it close valve, which can combine the disc sealing and seat sealing surface to achieve the close status. In the meanwhile, the valve can break off the media in pipeline .when opening the valve, stem and disc is disengaged. It plays the role of a check valve to prevent the media back flow. 2.This valve has a dual function ,it can cost savings and higher security. 3.Especially suitable for the installation location restrictions for special occasions.
Advantage 1.Bellow seal element. The key part of bellow sealed globe valves is metal bellow. It is the connection between cover and stem with automatic roll welding. The metal bellow can keep the stem part no leakage. 2.Benefit from the con and streamline shape design, the disc has a reliable seal and longer service life. 3.Double seal design(bellows+packing). Bellow and packing can protect against leakage and provide a excellent seal. 4.Grease nipple. It can direct lubricate the stem, nut and sleeve. 5.Ergonomic hand wheel. It provide longer service life and easier operation.
Competitive Advantage: 1. 18 Months Guarantee for quality. 2.OEM manufacturer, print client’s LOGO on the valve body. 3.Offer Operation Manual & Install Introduction for safety use. 4.Offer manufacturer’s reasonable price to win the market for both. 5.Accept any the third party inspection. 6.As a factory, every production process can be controlled during manufacture. 7.Offer inspection & testing reports for raw materials, production process, wall thickness, face to face dimension, pressure test, welding test, painting test, etc.

JIS 10K Globe valve also known as the door valve, belongs to the forced sealing valve, so when the valve is closed, must apply pressure to the disc, in order to force the sealing surface leakage.When the medium under the disc into the valve, the operating force to overcome the resistance, is the friction of the valve stem and packing and by the pressure of the medium produced by the thrust, the force to close the valve is greater than the force to open the valve, so the diameter of the valve stem to be large, otherwise the valve stem bending fault will occur.
ANSI 150LB Globe valve also known as the door valve, belongs to the forced sealing valve, so when the valve is closed, must apply pressure to the disc, in order to force the sealing surface leakage.When the medium under the disc into the valve, the operating force to overcome the resistance, is the friction of the valve stem and packing and by the pressure of the medium produced by the thrust, the force to close the valve is greater than the force to open the valve, so the diameter of the valve stem to be large, otherwise the valve stem bending fault will occur.
The opening and closing parts of the stainless steel flange globe valve are plug shaped disc, sealing surface is flat or conical surface, disc along the center line of the seat for linear motion.Stem movement, (common name: dark stem), also can be up and down rotary stem type, (common name: rising stem) globe valve refers to the closing member (disc) along the center line of the seat of the valve.
Brass globe valves are part of the globe valve family.Its main material is brass.
