Start-up valves

Maag's start-up valves are based on the proven single-piston design that operates without any additional seals. Their sturdy construction, available in all sizes and designs, guarantees reliable and leak-free operation for many years. In critical, e.g. highly-filled polymer melt applications, the hydraulic system could be completed with an anti-blocking mode (ABM).
