Three styles of modular fluid distribution manifolds were launched by Parker Hannifin. Two of the manifolds, the Hi-Pro Distribution Manifold (up to 6000 psi) and the Hi-Pro Air Header Manifold (up to 800psi), are based on ball valves for quick on-off control. Parker’s third option, the H-Series Distribution Manifold (up to 6000psi), provides a compact manifold body that accepts a user-defined choice of five or 10 metal-seated needle valves. www.parker.com
