FAQs: Custom Valve Components for Robotics Applications

These are the machined components that allow for the accurate control of motion conversion used in the electric, pneumatic, and hydraulic robotics actuators. These include linear actuators, which house either ball screws or lead screws, rotary actuators, which house gear trains or harmonic drives, and pneumatic cylinders, which have precision bore surface cylinders. Other examples include piston rods, which have tight straightness tolerances, gripper jaw mechanisms, mount flanges for servo motors, bodies of control valves, bearing blocks that support rotating shafts, end caps with integrated sealing grooves, and control bodies of fluid valves

Brass C36000 and C46400 enables cost-effective high-volume production for complex internal passages and also meets challenges for 16 bar pressures. Natural lubricity for valve spools and corrosion resistance to compressed air and hydraulic fluids complete this brass combination. Outstanding features for galvanized and extensive heated architectural applications, Aluminum 6061-T6 has enough strength for 10 bar pneumatic applications, excellent corrosion resistance and thermal conductivity, and lightweight construction. Stainless steel 303, 316, and 17-4 PH are strongest for 350 bar high-pressure hydraulic valves which is designed for corrosion resistance in washdown environments as well as wear hardened. For low-pressure applications which are cost sensitive, Engineering plastics like PEEK and Delrin provide chemical resistance and lightweight construction.

CNC turning is used to make cylindrical housings, piston rods, and shaft components, achieving concentricity tolerances of 0.001 inches. Precision Internal bearing bores are bored to tolerances of ± 0.0005 inches to within 0.4 Ra microns to meet bearing bores' surface to fit the bearing. Internal features of bearing housings are machined using multi-axis milling machines. Honing is performed to achieve cylinder bores with Ra less than 0.2 microns to reduce friction and wear on the seals. End caps and adjustment mechanisms are precision threaded by thread milling, and cross-drilling is used to make fluid passages, mounting holes, and arm linkage holes.

Tolerances of ± 0.0005 inches and concentricity of 0.001 inches between bores aid in the alignment and reduction of radial play. Piston rod straightness within 0.001 inches per foot, and cylinder bore diameter tolerances of ± 0.0003 inches aid in seal performance. Overall housing dimensions of ± 0.005 inches guarantee proper alignment with other components of the actuator and axial alignment hung on the housing.

Yes, we provide rapid prototyping to verify fit and test assembly, with same-day CAD-to-part capability available for critical projects. For custom automation cells and research platforms, we perform low-volume production of 20 to 500 brackets. For standardized robot models, we perform high-volume production of thousands to tens of thousands of brackets annually, incorporating complete dimensional inspection, flatness verification, and material certifications.

Yes, and all components are manufactured under ISO 9001 with complete material traceability, examination of dimensions by design, pressure-tested hydraulic and pneumatic components up to 300 bar, and documented motion components in industrial robotics for intricate requirements. Documentation includes positioning accuracy within 0.05 mm, controlled motion within 2% of a load, durability through millions of cycles, and within motion for programmable sequencing.

We provide comprehensive finishing solutions tailored to aerospace requirements:
Anodizing (Type II and Type III)
Passivation for corrosion resistance

Custom protective coatings and thermal barriers

Standard pneumatic valve bodies and manifolds, including Swiss turning, lapping, and quality verification, take 10–15 business days, whereas complex proportional valves with precision spools are 4–5 weeks. For rapid pneumatic system validation, we can complete prototype components for flow testing in just 7–10 days.

Yes! We create tiny valves for collaborative robot grippers which have port sizes under 2 millimeters, high-flow valves allowing rapid actuator response which achieve cycle times under 0.1 seconds, proportional valves used for precise force control in assembly applications where the flow can vary within 2 percent, high pressure hydraulic valves for heavy industrial robots operating at 250 bar, vacuum valves which assist in delicate part handling with response times under 50 ms, corrosion-resistant stainless valves for cleanroom and food processing robots, integrated valve manifolds consolidating 4 to 16 valve functions, and custom designs which soft-start valves to prevent shock loads and with low power consumption.

Fitting bearing bore dimensions within ±0.0005 inches allows the shafts to be mounted with minimal radial play and thus, minimize vibrations that will affect the positioning accuracy. A concentricity tolerance of 0.001 inches on concentric surfaces will maintain alignment and side loading, thus preventing premature bearing failure. Ra values of 0.2 microns or better on the bore surfaces will lower friction to the point where the actuation force will be less than 15 to 25, and extend the life of the seals beyond 10 million cycles. A straightness of 0.001 inches per foot on piston rods will prevent binding. The quality of the surface will contribute to maintaining leak rates in seals above the acceptable limit. The selection of materials will optimize the performance of the actuator by maintaining a proper balance of strength, weight, and corrosion resistance.
