KR pressure regulators

SHEARFLO® KR PRESSURE REGULATORS

• PacSeal Hydraulics’ KR pressure regulators are designed with ShearFlo® metal-to-metal sealing technology to ensure high cycle life and negligible internal leakage with superior contaminant resistance, making these valves perfectly suited for critical service applications in harsh and hazardous environments.
• KR regulators serve as pressure reducing and regulating valves to maintain downstream hydraulic system pressure at a desired value (set pressure) that is below that of the supply pressure. All pressure regulators are factory acceptance tested to guarantee conformance of the rated regulated outlet pressure. PacSeal’s ShearFlo® technology further provides high reliability and long service life.
• The outlet pressure is controlled by modulating the compression of springs that act on a pressurized piston either manually or with a failsafe motor. This in turn balances the hydraulic load inside the regulator body for an accurate and consistent set pressure.
• Available sizes range from 1/8” to 2” (NPT, SAE ORB, Code 61 or Code 62).
• View information for system integration guidelines, operation and troubleshooting.
• Accessories and repair kits are offered for all KR Pressure Regulators. For replacement parts, download the pressure regulator’s respective spec sheet and request a quote online or call PacSeal today; while referencing the part number, description, and quantity.

Features

• Made in the USA
• ShearFlo®sealing technology ensures a high cycle life and anti-wear design that is suitable for critical service applications, including contaminated fluids with high flow rates.
• An essentially zero leak, contaminant resistant metal-to-metal seal for the valve is accomplished by lapping and polishing hardened stainless steel sealing elements to exacting standards of finish and flatness.
• The sealing elements are spring preloaded and pressure energized, which maintains contact between the two sealing surfaces at all times to prevent contaminants from causing leaks and damage.
• Movement between the sealing surfaces maintains the lapped, flat surface to ensure a long life that renews with use.
• All KR pressure regulators are tested to PacSeal’s strict quality control standards for proper function and reliability.
• Every ShearFlo sealing component in a repair kit is inspected to ensure trouble-free performance after field maintenance and repair.
