MAC Valve Company has been building and maintaining a technical position in the design and manufacture of pneumatic and fluid valves, proportional valves, flow control and conventional technologies since 1948. With over 100 patents related to pneumatic valves and their auxiliary components, MAC is committed to designing technologically advanced industrial valve solutions to meet the unique and exacting needs of our customers. With operations on four continents and a network of MAC reseller agencies in every major industrial market, MAC provides support within the range to support our customers' needs to keep their machines consistently profitable 24 hours a day. American MAC provides our customers with reliable valves. We are committed to innovative, industry-wide valve design and reliable valve operation. Strong, high-quality parts are resistant to wear, and reducing the number of moving parts in the valve reduces wear points. Built-in wear compensation ensures lift valve seals work reliably, even after tens of millions of valve cycles. The valve is capable of high flow rate and short stroke, ensuring higher internal switching force and D-seal technology for precise control of internal friction.
