AR40K-N03E-Z

The SMC AR40K-N03E-Z pressure regulator is a versatile and reliable solution for controlling and maintaining consistent pressure in various fluid systems. This regulator, manufactured by SMC Corporation, is designed to provide precise pressure regulation with minimal pressure drop.

The AR40K-N03E-Z is a diaphragm type regulator, which means it utilizes a flexible diaphragm to separate process and control media. This design ensures superior media compatibility, as it eliminates the need for direct contact between the process and control fluids. The regulator is also available in various materials, including stainless steel and PTFE-coated materials, making it suitable for use in a wide range of industrial applications.

This particular model features a spring-loaded, non-lubricated, and adjustable stem design. The non-lubricated stem eliminates the need for regular maintenance, while the adjustable stem allows for easy pressure adjustments in the field. The regulator also includes a pressure relief valve, which helps protect against overpressure and ensures safe operation.

The SMC AR40K-N03E-Z is designed to handle a maximum working pressure of 10 bar (145 psi) and a maximum flow rate of 70 L/min (18.5 gpm). It is suitable for use with a wide range of fluids, including water, air, and various industrial chemicals.

The regulator is compact and lightweight, making it easy to install and integrate into various systems. It also includes a mounting bracket for convenient installation on a wall or other vertical surface. The regulator's operating temperature range is from -10 C to 60 C (14 F to 140 F), making it suitable for use in a wide range of environmental conditions.

The SMC AR40K-N03E-Z pressure regulator is an excellent choice for industrial applications where precise pressure control is essential. Its durable construction, ease of use, and versatility make it a reliable and cost-effective solution for maintaining consistent pressure in a variety of fluid systems.
