0G8841.5C

The Mercer 0G8841.5C 188655 New-No Box CRN Pressure Relief Valve is a high-performance safety device designed to protect against excess pressure in various industrial applications. This relief valve conforms to the CRN (Canadian Regulation Number) 278 standard for pressure relieving devices and is suitable for use with 1-1/2 NPT (National Pipe Thread) connections.

This Mercer relief valve is engineered to provide reliable pressure relief up to a maximum working pressure of 250 psi (pounds per square inch). Its compact design makes it an ideal solution for applications where space is limited. It is constructed from heavy-duty materials, ensuring durability and long service life.

The valve's New-No feature is a critical safety aspect. This means that the valve will open automatically if the set pressure is exceeded, but will not close until the pressure falls below the set point. This is particularly beneficial in applications where it is essential to vent excess pressure without risking the possibility of the valve closing prematurely.

The Mercer CRN Pressure Relief Valve is designed to maintain a consistent discharge flow rate during operation. This feature is crucial in applications where a consistent discharge flow is essential for maintaining system stability or safety. The valve's flow rate is determined by the size and design of the internal relief orifice, which is engineered to provide optimal performance for the specified application.

The valve's body and internal components are made from corrosion-resistant materials, making it a suitable choice for use in environments where exposure to corrosive substances is a concern. The valve's external surfaces are also finished with a durable coating that resists wear and tear, ensuring the valve remains in good working order even in harsh operating conditions.

The Mercer 0G8841.5C 188655 New-No Box CRN Pressure Relief Valve is a versatile and reliable safety device that offers excellent performance and durability. Its conformity to the CRN 278 standard and its ability to handle working pressures up to 250 psi make it a suitable solution for a wide range of industrial applications. Additionally, its New-No feature, compact design, and consistent discharge flow rate make it a preferred choice for applications where safety, reliability, and efficiency are paramount.
