Internal passages connect the pressure, return, actuator and control ports. Mounted cartridge or subplate valves open, close or meter these routes to regulate flow direction, pressure and volume. The block routes the fluid while the installed valves perform the control logic.

Manifold blocks provide compact circuit integration, fewer external connections, lower leakage risk and faster system assembly. Their limitations are higher design and machining requirements, restricted access to internal passages, demanding deburring and cleanliness control, and limited modification after the flow paths have been machined.

Before machining, Weldo verifies the material grade, heat or lot number, delivery condition, certificate, blank size and machining allowance. Critical forgings and pressure-bearing blanks receive drawing- or quality-plan-specified NDT: ultrasonic testing for internal discontinuities, with magnetic-particle or dye-penetrant testing for surface cracks where applicable. Large or distortion-sensitive blanks are stress-relieved or aged before stable datums are established.

Rating is based on material condition, passage layout, minimum wall, thread engagement, plugs, peak pressure and fatigue duty. The approved design is verified to the specified pressure-test plan.

Project documentation can include material certificates, dimensional reports, finish records, cleanliness results and pressure or leakage test records when stated on the purchase order.

Only an engineering-approved repair is acceptable. Cracks, intersected circuits or insufficient pressure-wall thickness normally require rejection. Any flow-path repair requires renewed inspection and pressure testing.

It is useful for curved passages, major weight reduction and highly integrated layouts. Printed parts still require heat treatment, CNC finishing, internal cleaning, inspection and pressure verification.

Clean ports are capped, sealing faces and threads are protected, steel parts receive compatible corrosion protection, and blocks are separated with non-abrasive packaging.
