Reliable Pressure Regulation for Pneumatic Systems

The MAR301 Pressure Reducing Valve delivers dependable control over downstream air pressure, maintaining consistency even when inlet conditions vary. Ideal for industrial and pneumatic applications, its compact, cylindrical shape allows for flexible mountingboth panel and inline configurations are supported. The visual gauge mounting provides at-a-glance verification of set pressure, improving operational convenience and safety on the shop floor.

Easy Installation and Versatile Applications

Designed to fit seamlessly into new or existing air systems, the MAR301 valve supports BSPT female connections in common sizes. Vertical installation is recommended for optimal accuracy. The manual adjustment knob, combined with a high-tolerance rating of 0.2 bar, ensures precise pressure setting to meet your systems needs. The valves smooth, anodized finish resists corrosion, making it suitable for harsh industrial environments.

FAQs of Pressure Reducing Valves Model: MAR301:

Q: How is the MAR301 pressure reducing valve installed in an air system?

A: The MAR301 can be mounted either on a panel or inline within your pneumatic system. It accepts BSPT female threads (1/4", 3/8", or 1/2") and should ideally be installed in a vertical position for maximum accuracy. Simply connect to your existing air line, ensuring proper flow direction.

Q: What is the recommended operating pressure and temperature range for the MAR301 valve?

A: This valve is designed for inlet pressures up to 10 bar (145 psi) and can regulate downstream pressure within the 0.5 8 bar (7 116 psi) range. It operates reliably at temperatures from 5C to 60C.

Q: Where can the MAR301 valve be used effectively?

A: The MAR301 is suited for use in industrial pneumatic systems and air lines, functioning as a critical accessory for maintaining constant downstream pressure in machinery, equipment, or production processes.

Q: What makes the MAR301s design advantageous for system integration?

A: Its compact, cylindrical form with anodized aluminum alloy construction ensures a lightweight yet durable build. The relieving diaphragm type provides stable regulation, while its easy adjustment and visual gauge mounting enhance usability and system monitoring.

Q: How does adjusting the MAR301 valve benefit pneumatic applications?

A: By precisely setting the downstream pressure with the manual adjustment knob, the valve maintains constant output regardless of input fluctuations. This consistency prevents equipment damage, ensures product quality, and improves operational efficiency.

Q: What materials are used in the MAR301 and how do they contribute to its performance?

A: The body is made from high-tensile strength aluminum alloy with an anodized coating for superior corrosion resistance. Nitrile rubber (NBR) seals provide excellent durability and minimize leaks, even under demanding industrial conditions.
