As one of the china ball valve manufacturers, ZECO always adhere to exceed customer expectations, to provide customers with more international standard valve services and products as the ultimate goal.

Description of Metal Seated Butterfly Valve:

ZECO metal seated butterfly valve body and seat sealing surface of the use of metal materials, and surface hardening treatment, belongs to the metal against metal to seal structure, even in a line need frequent opening and closing, the valve can still maintain effective sealing performance, and in view of the existing medium wear condition, can use targeted for surface hardening treatment to achieve higher than medium wear hardness, so as to improve the service life of the valve. ZECO is a global professional supplier of hard seal butterfly valves. ZECO's professional technology, production process and maintenance guidance have made ZECO a leader in the field of valves.

Features of Metal Seated Butterfly Valve:

1. ZECO metal seated butterfly valve made in china can realize bi-directional sealing, the concept of bi-directional sealing is that no internal leakage can be guaranteed in the valve body no matter from the forward pressure of the valve body or the reverse pressure of the valve body, and can meet the zero leakage requirement of API 598 international standard;

2. ZECO metal seated butterfly valve adopts double security architecture design, disc, stem and sealing surface directly under medium pressure in the pipeline and the wear and tear, ZECO to prevent possible pipeline due to various problems caused by the butterfly plate deformation, dislocation of stem, the phenomenon such as sealing face fit, the butterfly disc up and downside is equipped with two separate independent thrust ring ensure the normal operation;

3. ZECO metal seated butterfly valve is designed with a replaceable sealing ring. The sealing surface of butterfly disc and butterfly disc are independent of each other, and the valve seat and valve body are independent of each other, so butterfly plate sealing ring and valve seat can be replaced at the same time. When the sealing ring or seat is damaged, only the sealing ring and seat need to be replaced;

4. The valve seat of ZECO butterfly valve adopts the structure of forged valve seat made of all-metal alloy steel. Its hardness is extremely high, it can be used in abrasion media, and it is resistant to high temperature and high pressure.
