RV 66S-ST is a type of pressure reducing valve specifically designed for controlling pressure of high-pressure systems. This type of valve is widely used across industries for applications such as power plants, fuel systems, chemical plants, and in other industries where pressure control is required.

The RV 66S-ST is a two-stage pressure reducing valve which consists of two poppet valves housed in a pressure tight cylinder. The upper poppet valve opens and closes by the action of the pressure differential across its seat. When the pressure exceeds the presetting, the poppet valve opens to reduce the pressure to the required level. The lower poppet valve is set at the desired pressure level and when the pressure reaches this level, the poppet closes to seal the valve and keep the pressure steady.

The RV 66S-ST features a variable orifice and a spring-loaded reset mechanism. The size of the orifice can be adjusted using the reset mechanism to accommodate different pressure settings. This allows it to be used in applications which require multiple pressures such as fuel systems where different pressures are needed for different fuel types. The valve should be initially preset to the maximum pressure setting required and then adjusted accordingly.

The RV 66S-ST is also designed with an integral strainer which captures dirt and other contaminants which can harm the internal parts of the valve. This helps to keep the valve in good working condition and extend its life.

The RV 66S-ST is used for a variety of applications such as in power plants to reduce the pressure of steam, in fuel systems to regulate the pressure of fuel supply, and in chemical plants to regulate the pressure of chemicals used in production. It is also widely used in marine applications to control the pressure of fluids and gases.

The RV 66S-ST is a robust and reliable pressure reducing valve which is designed for long-term and reliable service in demanding industrial applications. It features an adjustable orifice, an integral strainer, and a spring-loaded reset mechanism which makes it a reliable choice for controlling pressure in high-pressure systems.
