Z41W-300Lb flange connection API cast steel gate valveDetailed product description：

Z41W-300Lb flange connection API cast steel gate valve reference standard:

Design and Manufacturing: API 600
Structural length: ANSI B 16.10
Pressure and temperature rating: ANSI B 16.34
Testing and Inspection: API 598

Z41W-300Lb flange connection API cast steel gate valve Purpose:

The flange connected API cast steel gate valve is suitable for cutting off or connecting pipeline media in various working conditions such as petroleum, chemical, and thermal power plants with ANSI Class 150-2500 and working temperature<600 ℃. Applicable media include water, oil, steam, etc. The operation modes include manual, gear transmission, electric, pneumatic, etc.

Product Structure Features:

1. The product is designed and manufactured according to API standards, with reliable sealing, excellent performance, and can be used in conjunction with imported equipment.
The sealing of the gate and valve seat above 2.600Lb is made of Stellite cobalt based hard alloy welding, which is wear-resistant, high-temperature resistant, corrosion-resistant, has good scratch resistance, and has a long service life
3. The valve stem has undergone quenching and surface nitriding treatment, providing excellent corrosion resistance and abrasion resistance.
4. Adopting a wedge-shaped elastic gate structure, rolling bearings are installed on medium and large diameters for easy opening and closing.
5. The valve body material variety is complete, and the packing and gasket are reasonably selected according to actual working conditions or user requirements, which can be suitable for various pressure, temperature, and medium working conditions.
6.1500LB and 2500LB chambers adopt a pressure self tightening sealing structure. The sealing performance increases with the increase of internal pressure, and the reliability is high.
7. The reverse seal is made by connecting the sealing seat with stainless steel threads or welding austenitic stainless steel on the body. The reverse seal is reliable, and the replacement and maintenance of the packing can be carried out without stopping the machine, which is convenient, fast and does not affect the operation of the system.
