KW900重型阀门专用密封脂
KW900 Special sealing grease for heavy-duty valves
KW900为重型阀门专用密封脂，本产品可以有用于压裂中闸阀的密封与防护，可以耐受产生的各种烃类，以及H2S & CO2浓度较高的物质。KW900的高粘附性特性可以增强腔体的滞留性， 同时还增强了润滑性能，可以在不同高压环境下保护阀门的密封面。
KW900 is a special sealing grease for heavy-duty valves. This product can be used to seal and protect gate valves during fracturing. It can withstand various hydrocarbons produced, as well as substances with high H2S & CO2 concentrations. The high adhesion characteristics of KW900 can enhance the retention of the cavity, and also enhance the lubrication performance, which can protect the sealing surface of the valve in different high-pressure environments.
