Product main features
1.Standard high-quality 304 parts, more resistant to moisture, open-air environment
2.Hand wheel surface thermal spraying epoxy resin powder, beautiful easy to clean, corrosion-resistant, perfect combination withthe valve life
3.Copper parts using standard HPb59- 1 bar by forming multi-channel hot forging process, not annealed after forging, dense andweather resistance, not easy cracking, no internal stress
4.Seals of EPDM rubber, water aging performance, life in the water longer than the NBR, guaranteed for 50 years
5.Rubber vulcanization using advanced technology to ensure that iron is not exposed, do not use contact with water, rust will not form'
6.AlI heat flow valve cavity coating "AkzoNobel" of "RESCOAT' pure epoxy powder, small flow resistance. Resistant 1500KV spark test,will not rust, effectively blocking the cast of secondary pollution of water. [Note: This must refer to AkzoNobel's registered mark,to be described]
