About Daman Products
Precision Hydraulic Manifold & Fluid Power IntegrationHelios Technologies
Daman Products, founded in 1976 in Mishawaka, Indiana, is a leading designer and manufacturer of precision hydraulic manifolds and fluid conveyance products serving original equipment manufacturers and the aftermarket. Now part of Helios Technologies (a partner with Sun Hydraulics), Daman combines 45+ years of manifold engineering expertise with state-of-the-art CNC machining and Lean manufacturing to deliver standard catalog manifolds and fully-custom engineered solutions.
The Daman product portfolio includes standard manifold platforms (subplates, headers, junction blocks, sandwich modules) optimized for common hydraulic circuits, alternative material options (ductile iron, aluminum, ductile stainless steel), specialized surface treatments (nickel plating, hard-chrome, epoxy coating) for corrosion resistance, and complete custom assemblies capable of handling 20,000+ lb casting weight with integrated valve cavity networks and pressure/return/pilot galleries.
Daman's CNC machining facilities enable rapid prototyping and custom manifold fabrication with cavity design, porting, cavity liners, integrated pilot-operated logic, and testing per customer specifications. Standard manifolds with 2+ million variant combinations serve diverse industries: machine tools, construction equipment, farming machinery, mining, energy, agricultural equipment, shipbuilding, and entertainment/amusement rides.
Applications range from simple single-valve sandwich stacks to complex multi-section integrated manifolds controlling synchronized motion, load sensing, proportional pressure/flow, and safety interlock functions. Daman's integration approach reduces external hose runs, improves system reliability, and decreases assembly complexity.
ChatMRO connects hydraulic system engineers and OEM procurement teams instantly with the right Daman manifold solution—specify your pressure rating, flow requirement, number of valve functions, control method (pilot-operated, pressure-compensated, load-sensing), and any material/surface-treatment constraints, and our AI surfaces matching standard manifolds or custom engineering services from our indexed 30M+ component database.

Frequently asked questions
What's the advantage of an integrated manifold versus multiple external valves and hoses?
Integrated manifolds reduce external hose counts by 80%+, eliminating leak points, reducing weight, simplifying routing in space-constrained equipment, and improving response time (shorter pilot lines = faster valve actuation). Single-source responsibility for manifold assembly also improves quality assurance compared to assembling components from multiple suppliers.
Can Daman custom-design a manifold if I have a complex, multi-function hydraulic circuit?
Yes—that's Daman's core expertise. Provide circuit diagrams, pressure/flow requirements, control logic, and any material/environmental constraints. Daman engineers design cavity networks, pilot galleries, and sandbox modules, then fabricate and pressure-test the complete assembly. Lead times for custom manifolds typically range 8–12 weeks depending on complexity.
What surface treatments does Daman offer for manifolds in corrosive environments?
Standard ductile iron; aluminum for weight-sensitive applications; stainless steel for seawater/chemical; nickel plating, hard-chrome, or epoxy coating for corrosion resistance. Choose based on fluid type and environmental exposure. Chemical environments and offshore applications typically require stainless + specialized coatings; standard industrial uses ductile iron.
How do I transition from multiple external valves to an integrated Daman manifold?
Provide Daman your current schematic (showing valve types, pilot/load-sensing logic, flow paths). Their engineers design a manifold replicating your logic while optimizing cavity layout. The manifold will have fewer external hoses/fittings; internal galleries replace external lines. Transition usually requires minimal system redesign beyond hose routing.
What's the typical cost difference between a standard Daman manifold and a fully custom-engineered design?
Standard manifolds cost less per unit but may require external valve stacks to supplement functionality. Fully custom designs cost more upfront but integrate all functions, reducing external components and assembly labor. For OEM production runs (100+ units), custom manifolds often have lower total cost per machine despite higher per-unit manifold price.
