What PacSeal Hydraulics does

PacSeal Hydraulics, Inc. is a privately-held, founder-owned manufacturer of high-performance hydraulic fluid power control components, headquartered and produced at a single facility in Brea, California. Founded in 1987 and ISO 9001:2015 certified since 2004, the company builds its product portfolio around ShearFlo®, a proprietary metal-to-metal sealing technology that uses lapped and polished hardened stainless steel seal rings and rotors to deliver negligible internal leakage and contamination resistance in high-pressure hydraulic circuits.

The product line consists of directional control valves (SV, SVS subsea, SVT splash zone, LSV linear), KR pressure regulators, check valves, relief valves, hydraulic accumulators, and supporting manifolds, actuators, and repair kits. The technology is qualified for safety-critical applications — including BOP control systems for onshore and offshore drilling, subsea ROV panels, aerospace hydraulic control, and harsh-environment industrial equipment — and is protected by USA Patent #9587454 covering an integral manifold design that reduces installed footprint by 50%, plus two patent-pending designs.

PacSeal sells primarily through direct enterprise field sales (quote-based, no public pricing or e-commerce), supported by a global distributor network and international shipping via customer-arranged freight forwarders. Revenue is generated from hardware sales of standard catalog components, custom-engineered solutions for non-standard applications, and an aftermarket stream of OEM repair kits and accessories. Marketing relies on industry trade shows (notably the Offshore Technology Conference), technical content marketing, and a 2024 catalog integration into Famic Technologies' Automation Studio™ circuit simulation software.

Revenue model

1. Fluid Power Control Components: Sale of manufactured hydraulic control components including directional control valves (SV series, SVS subsea, SVT splash zone), pressure regulators (KR series), accumulators, relief valves, check valves, and hydraulic manifolds. Products are sold as one-time purchases with optional accessories and repair kits for aftermarket support.
2. Repair Kits and Spare Parts: Aftermarket revenue from OEM repair kits (O-ring kits, seal kits, minor repair kits, major repair kits) for all SV directional control valves and KR pressure regulators. Also includes accumulator accessories, actuator brackets, and nameplates.
3. Custom Engineering Solutions: Custom solution engineering for applications where standard products do not fit project requirements. The company engineers custom solutions that withstand harsh conditions and outperform other valve-sealing technologies.

Core offering

PacSeal Hydraulics designs, engineers, and manufactures high-performance hydraulic fluid power control components built around its proprietary ShearFlo® metal-to-metal sealing technology. The portfolio includes directional control valves, pressure regulators, accumulators, manifolds, check valves, relief valves, and air remote controls, primarily serving oil and gas drilling, aerospace, subsea, and industrial applications. The company also produces OEM repair kits and offers custom engineering solutions for non-standard requirements.

Product overview

PacSeal Hydraulics is a manufacturer of high-performance fluid power control components centered around its proprietary ShearFlo® metal-to-metal sealing technology. The product portfolio consists of directional control valves (SV series in five sizes from SV-12 to SV-200, plus SVS subsea and SVT splash zone variants), KR pressure regulators (eight sizes from KR-12 to KR-200), linear valves, check valves, and relief valves—all featuring ShearFlo® zero-leak sealing. Supporting these core products are bracket mounted actuators, SVX integral actuators, hydraulic manifolds (integral, conventional, and accumulator types), air remote control systems, bladder accumulators, and comprehensive accessory/repair kit lines. The components are designed for critical service applications in oil and gas, aerospace, subsea drilling, and industrial hydraulics, with a focus on contamination resistance and high cycle life.

Partnerships

One partnership is on record.

• Famic TechnologiescoreTechnology or Integration · 1 January 2024PacSeal Hydraulics collaborated with Famic Technologies to make its catalog of high-performance fluid power controls available in Famic's Automation Studio™ simulation software. Users of Automation Studio™ can now create and simulate hydraulic circuits using any configuration of PacSeal's directional control valves, pressure regulators, relief valves, check valves, hydraulic manifold assemblies, and accumulators. The catalog includes all schematic symbols with individual component parameters (Cv, flow rate, pressure drop, etc.) for accurate circuit modeling. This partnership enables engineers worldwide to design, simulate, and validate hydraulic circuits with PacSeal components before physical implementation.
