The use of floating ball valve produced by Simac is based on the temperature and pressure of the medium. There are four kinds of valve seat materials, which are selected according to the temperature.
The use of floating ball valve produced by Simac is based on the temperature and pressure of the medium. There are four kinds of valve seat materials, which are selected according to the temperature.
Part is the fixed ball valve range of CLASS150, 300 and PN16, 25, 40. For GM seats and RPPL seats, they are not limited by this table.
The valve body class in the table is in accordance with ANSI B16.34. Seat rating is as per BS5351 standard. (But the full bore 250mm and the necking type 300mm is according to TJ standard)
Simac production of floating ball valve generally DN250 ~ diameter (NPS10-NP12) using turbine driver. The operation of the vortex rod-turbine is light and labor-saving and flexible. Can also be based on user requirements for DN15 ~ DN150 floating ball valve using turbine drive. A fully sealed scroll bar-turbine can be used for outdoor piping valves.
Wrench
According to the operating torque of the floating ball valve, the size of the diameter and other factors, the wrench structure is divided into two types, the selection of the material must be considered from the fire, high temperature, deformation and other factors.

A cast steel floating ball valve is a crucial component in various industrial applications for fluid control.
**1. Robust Construction** Cast steel is used in its manufacturing, which endows the valve with excellent strength and durability. This material can withstand high pressure and extreme temperature conditions, making it suitable for use in demanding environments such as oil refineries, chemical plants, and power generation facilities.
**2. Floating Ball Design** The floating ball within the valve plays a key role. It is free to move slightly, allowing for a tight seal against the valve seats. This design ensures effective shut - off of the fluid flow, preventing leakage even under high - pressure differentials.
**3. Precise Flow Control** The valve offers precise control over the flow rate of the fluid. By adjusting the position of the ball, operators can regulate the amount of fluid passing through the valve with a high degree of accuracy.
**4. Corrosion Resistance** Cast steel can be treated or alloyed to have good corrosion - resistant properties. This protects the valve from the corrosive effects of various fluids, extending its service life and reducing maintenance costs.
**5. Easy Installation and Maintenance** It is designed for easy installation in piping systems. And with its simple structure, routine maintenance such as inspection and replacement of parts can be carried out relatively easily.
In conclusion, the cast steel floating ball valve combines strength, reliability, and efficient flow control, making it a top - notch solution for fluid - handling systems in many industries.
