R70-Series Air-Operated Pressure Regulator (Positive Control)

Product Code: R7030P/R7015P

High-pressure air-operated regulators designed for precise control of adhesives, sealants, and greases. Ideal for stable dispensing in automated or manual fluid systems handling viscosities up to 1,000,000 cP.

Precise Pressure Control

Ensures consistent fluid output by maintaining stable working pressure (2–30 MPa) even during pump changeover.

High Pressure Capability

Handles inlet pressures up to 50 MPa (7,250 psi), suitable for high-viscosity materials and demanding industrial applications.

Wide Viscosity Range

Compatible with materials from 1 cP to 1,000,000 cP, covering greases, sealants, and thermal interface materials.

Reliable, Durable Construction

Wetted parts made from stainless steel, carbon steel, PU, NBR, and PTFE for corrosion resistance and long service life.

Easy Integration & Maintenance

Compact 104 × 104 × 134 mm design, simple air control connection (PT 1/8″), and optional maintenance kits for quick service (305101 / 305201).

Stable Flow Accuracy

Dampens flow surges during pump changeover, providing uniform dispensing and avoiding material inconsistency.

Feeding high-viscosity adhesives, sealants, and greases from 1–5 gallon pails to automated or manual dispense points.
Stabilizing fluid output pressure during pump changeover to prevent bead irregularity or over-dispense.
Providing precise control for non-stop feed systems, ensuring smooth and continuous material supply in production lines.
Maintain accurate mixing ratios of dual-component materials such as epoxies, polyurethanes, and silicones in 2K dispensing system.
Support precise dosing and bead control for applications requiring high reliability and minimal material waste.
