Pneumatic Quick Exhaust Orifice Plate

The Pneumatic Quick Exhaust Orifice Plate enables direct exhaust at the actuator port, eliminating dependency on centralized manifold venting. This configuration reduces return stroke lag by minimizing pressure accumulation in the cylinder bore during depressurization. Shorter exhaust pathways reduce system response time and dynamic losses, which is critical in high-speed automation where repeatability and timing accuracy are paramount.

Orifice Diameter

Range – 0.5–5.0 mm; Tolerance – ±0.01 mm

Plate Thickness

Up to 15 mm

Overall Dimensions

OD – 20–100 mm (±0.1 mm); Shape – Round/Square (custom profiles available)

Product Description

The internal profile of the Pneumatic Quick Exhaust Orifice Plate is precisely engineered to manage pressure decay in a controlled manner, avoiding flow turbulence and shock propagation. Orifice sizing is matched to the cylinder’s Cv requirements, ensuring that pressure release occurs uniformly across cycles. This level of control becomes necessary in applications demanding tightly synchronized multi-axis pneumatic systems with variable stroke lengths and velocities.

Corrosion Protection

Anodizing (Aluminum, 15–25 µm), Passivation (Stainless Steel, ASTM A967), Electroless Nickel

Certification Standards

ISO 9001:2015, ISO 4414 (Pneumatic Standards), RoHS/REACH Compliant

Technical Advantages

The Pneumatic Quick Exhaust Orifice Plate has no moving parts, making it immune to common mechanical wear or seal degradation issues seen in traditional quick exhaust valves. Its passive flow-based operation ensures consistent performance across millions of cycles, even in harsh industrial environments where particulate contamination or lubrication inconsistency would normally compromise mechanical valve integrity. 

By introducing a fixed flow resistance at the exhaust port, the Pneumatic Quick Exhaust Orifice Plate acts as a passive impedance barrier, helping to decouple upstream and downstream pressure fluctuations. This characteristic is essential when maintaining actuation sequence timing under variable load conditions or when working with parallel cylinders in coordinated motion. It supports pressure zone integrity without adding complexity to the pneumatic logic.

Industry Applications

Automated Assembly Lines

Enables faster cylinder return strokes, improving cycle times in repetitive linear operations like pressing, riveting, or component indexing. 

Pneumatic Pick-and-Place Systems

Reduces exhaust lag in end-effector actuators, supporting high-speed part transfer in synchronized multi-axis handling equipment. 

Robotic End-of-Arm Tooling (EOAT)

Improves actuation response in compact tooling setups where space limitations prevent use of full-size quick exhaust valves. 

Packaging Machinery

Stabilizes exhaust flow in high-cycle sealing and clamping stations, maintaining consistent pressure profiles during stroke transitions. 

Textile Automation Equipment

Supports rapid actuator cycling for fabric tensioning or cutting units where precise exhaust timing is required under continuous operation. 

Material Diverters and Sorting Systems

Maintains timing accuracy in pneumatic diverter arms by preventing exhaust backpressure during rapid directional shifts. 

 

Compact Integration for System Envelope Constraints

The Pneumatic Quick Exhaust Orifice Plate is designed for inline integration between the actuator and fitting interface, occupying minimal physical space while delivering high exhaust performance. This compact form factor supports systems with strict dimensional constraints such as robotic end-effectors, panel-mounted assemblies, or embedded tooling blocks. Its installation does not require rerouting of pneumatic lines or additional bracketry. 

The Pneumatic Quick Exhaust Orifice Plate maintains a stable exhaust profile regardless of downstream backpressure variation caused by fluctuating loads or line obstructions. This ensures that actuator retraction occurs at a consistent rate, supporting more predictable control behavior. Applications involving dynamic mass shifts, such as vertical lifts or telescopic slides, benefit from this exhaust consistency to avoid timing errors or actuator drift.

Having Doubts? Our FAQ

Check all our Frequently Asked Question

How does Frigate ensure compatibility of Pneumatic Quick Exhaust Orifice Plates with non-standard cylinder port geometries?

Frigate evaluates port thread specifications, sealing surfaces, and mounting tolerances to ensure proper plate-to-cylinder alignment. Custom plates can be machined to match special bore sizes or manifold interfaces. This ensures consistent exhaust performance even in non-standard actuator setups. Compatibility is validated through CAD fitment checks and pneumatic simulation data. 

What makes Frigate’s Pneumatic Quick Exhaust Orifice Plate suitable for high-frequency actuation beyond 30 cycles per minute?

Frigate uses optimized orifice profiles to maintain steady Cv values under fluctuating upstream pressures. The passive design allows uninterrupted flow without fatigue-related failure modes. All plates are validated using high-cycle endurance testing under thermal and pressure stress conditions. This ensures stable exhaust behavior over extended duty cycles. 

Can Frigate supply Pneumatic Quick Exhaust Orifice Plates with flow coefficients tailored to low-pressure (below 3 bar) systems?

Yes, Frigate offers orifice plates calibrated for low-pressure pneumatic environments requiring precise exhaust metering. Plate geometry is adjusted to prevent under-damped motion or actuator bounce at reduced pressures. Flow simulations are used to match orifice dimensions with required exhaust times. Final Cv values are confirmed through bench testing. 

What quality checks does Frigate implement for Pneumatic Quick Exhaust Orifice Plates before shipment?

Each orifice plate is tested for dimensional accuracy using CNC-based metrology systems. Flow characteristics are verified through leak testing and Cv validation under pressurized air. Visual inspections confirm burr-free edges and sealing surface integrity. Batch traceability is maintained through serial coding for performance tracking and replacement planning.
