Floin Valves And Instruments

The SVSJ 510 Steam Jacket Safety Valve is engineered with a thermal insulation steam jacket surrounding the valve body to maintain a stable temperature and prevent the solidification or crystallization of the medium inside. Continuous steam circulation through the jacket’s inlet and outlet ensures effective heat retention, while the sealing face surfaces are also flushed with steam to enhance sealing reliability and prevent material buildup on the seat.

This model, SVSJ 510, is available in sizes ranging from 25 NB to 300 NB, with flanged end connections. It is constructed from high-quality materials including Carbon Steel (CS), Stainless Steel 304 (SS304), and Stainless Steel 316 (SS316), and is manufactured under the Floin brand.

The valve is particularly well-suited for handling temperature-sensitive or high-viscosity media, making it ideal for use in chemical, petrochemical, and other process industries where maintaining consistent media flow is critical

Key Features:

• Pressure Rating: Available in regular ISQ or customized pressure settings based on application needs.

• End Connection: Offered with screwed or flanged ends for flexible installation options.

• Port Size: Full nozzle design ensures efficient flow and pressure relief.

• Size Range: Available from 25 NB to 300 NB to suit various system capacities.

• Body Material: Constructed from CI, WCB, CF8, CF8M, or customized materials to meet specific operating environments and fluid compatibility.

Certainly! Here is a clear and concise rewritten version of your CF8 Relief Safety Valve description in full sentence form:

The CF8 Relief Safety Valve is a safety or safety relief valve manufactured in compliance with API and ASME codes. It is a full-lift, pop-type valve available in both screwed and flanged models, featuring a standardized orifice for consistent performance. The valve is available in sizes ranging from 15 NB to 300 NB, with sizing based on API RP 520 and design standards as per API 526 and API 520.

The valve operates by lifting its disc off the seat when the inlet static pressure exceeds the set pressure, initiating the compression of the internal spring. As the pressure rises further, the disc continues to lift. To achieve full lift with minimal overpressure, the disc is specially designed—typically equipped with a shroud, skirt, or hood—to allow rapid opening. When fluid enters the chamber, it exposes a larger area of the shroud to pressure, increasing the lift force and triggering a fast-opening response.

Reseating occurs once the pressure is reduced. However, due to the larger surface area of the disc remaining exposed to fluid pressure, the valve will not immediately close at the original set pressure. It only closes after the pressure drops further—this difference is referred to as blowdown. To fine-tune reseating and blowdown performance, many valves include a blowdown (nozzle) ring, allowing for more precise control. Additionally, an upper blowdown ring, usually factory set, compensates for fabrication tolerances and ensures optimal chamber geometry.

These safety relief valves are ideally suited for non-compressible fluids such as water, oil, and other liquids. Immediate full-flow discharge is not necessary in liquid systems, as even a small flow significantly reduces pressure. As a result, the valve opens and closes gradually, discharging the fluid safely to a low-pressure return point in the system

Relief Safety Valve – Designed specifically for non-compressible fluids such as water and oil, these safety relief valves do not require immediate full-flow discharge. Even a small flow significantly reduces overpressure, allowing the valve to open and close the socket and seat gradually, safely discharging liquid back to a low-pressure point in the system.

Key Features:

• Material: Available in WCB, CF8, and CF8M to suit various application needs and environmental conditions.

• Media: Suitable for handling liquids.

• Cap Type: Closed cap design for enhanced safety and protection.

• Pressure: Customizable to meet specific system requirements.

• Spring: Made from high-quality spring steel for reliable and consistent performance.

The Open bonnet type safety valve is, allowing the spring chamber to communicate with the atmosphere, which is beneficial to reduce the temperature of the spring, and is mainly suitable for containers of high temperature gas in which the medium is steam. Open bonnets are usually advantageous when the safety valves are used on high temperature fluids or for boiler applications.
