Our valve connection standards include DIN, ASME, JIS, GOST, BS etc., it’s easy for customers to choose the suitable valve, help our customers reduce their stock.
Our valve has standard thickness according to GB26640, makes it capable of holding high pressure when needed.
The valve body use GGG50 material, has higher mechanical property, rate of spheroidization more than 4 class, makes the ductility of the material more than 10 percent. Compared to regular cast iron, it can suffer higher pressure.
Our valve seat use imported nature rubber, with more than 50% of rubber inside. The seat has a good elasticity property, with long service life. It can be open and close more than 10,000 times with no damage for the seat.
The valve seat is wide edge seat, sealing gap is wider than regular type, makes the sealing for connection easier. Wider seat also easy to install than narrow seat. The stem direction of the seat has lug boss, with O ring on it, archive the second sealing of the valve.
The valve seat with 3 bushing and 3 O ring, helps supporting the stem and guarantee the sealing.
Each valve should be cleaned by ultra-sonic cleaning machine, in case of contaminant left inside, guarantee the cleaning of the valve, in case of pollution to the pipeline.
The valve body use high adhesive force epoxy resin powder, helps it adhere to the body after melting.
Frequently Asked Questions
What international connection standards do the valves comply with?
Our valves comply with various global standards including DIN, ASME, JIS, GOST, and BS, allowing customers to easily match requirements and lower stock holding.
What are the benefits of using GGG50 ductile iron for the valve body?
The GGG50 material features a high spheroidization rate (class 4+) and elongation exceeding 10%, giving the valve body higher mechanical strength and significantly better pressure resistance than standard cast iron.
How does the valve ensure long service life and tight sealing?
The valve seat is made with imported natural rubber (over 50% rubber content) supporting over 10,000 cycles without damage, combined with a 3-bushing and 3-O-ring structure that secures secondary stem sealing.
What are the advantages of a wide edge seat design?
The wide edge seat provides an extended sealing gap that makes flange sealing tighter and installation easier compared to conventional narrow seat designs.
How is cleanliness and surface protection ensured during production?
Each valve undergoes ultrasonic cleaning to prevent internal media pollution, and the exterior is coated with high-adhesion melt-bonded epoxy resin powder for maximum corrosion resistance.
