Product Description

Our Progressive Divider Valve Check Valves are engineered to secure fluid direction and prevent backflow inside high-frequency automatic lubrication networks and commercial auto lube systems. Designed as an inline or port-mounted single-direction controller, this high-precision non-return valve safeguards your progressive divider valve blocks by preventing lines from draining under gravity or back-pressure. By enforcing a strict one-way flow, it ensures precise, predictable volumetric grease or oil delivery to critical machine bearings.

As a prominent global OEM manufacturer and bulk supplier, we produce these high-performance fittings for central lubrication across premium material profiles. Our components are available in heavy-duty carbon steel finished with high-durability, corrosion-resistant Zinc-Nickel plating (Cr-VI free), or in top-tier Marine Grade Stainless Steel (1.4401 / 316 / V4A) to withstand the most aggressive chemical and offshore environments.

Core Technical Blueprint & Thread Systems

The Extra Light LL Series Advantage: Optimized primarily around the compact Extra Light (LL) Series standard, these check valves feature a space-saving design with small wrench sizes (typically SW 11 to SW 12), ensuring an easy fit inside tight, multi-port divider valve manifolds. They accommodate low-pressure and mid-pressure lines using standard 4mm, 6mm, or 8mm metric tubing lines.
Multi-Market Port Thread Machining: To fit seamlessly into various international block architectures, the inlet stud base is precision-machined across multiple industry-standard thread configurations:
- Metric Threads: Available in standard straight M10x1 profiles or specialized Metric Taper Threads (M10x1 keg) for solid metal-to-metal flank locking.
- BSPT Taper Threads: Features British Standard Pipe Taper profiles (R 1/8 BSPT) optimized for traditional global plumbing blocks.
- NPT Taper Threads: Machined with an American National Pipe Taper profile (1/8 NPT) to easily satisfy North American instrumentation and process system layouts.

Application & Compliance Standards

Bite Type Sealing Integrity: The outlet end of the valve features a standardized 24° internal cone seat built in full compliance with DIN 2353 and ISO 8434-1 standards. When tightened, it drives the cutting ring securely into the lubrication tubing wall, creating an unyielding mechanical connection that handles continuous high-vibration machine cycling without backing out or weeping.
Global Interchangeability: Engineered to align with leading international fluid-handling benchmarks, these non-return valves provide a reliable, drop-in replacement for worn or leaking port fittings in any existing setup. They are the preferred selection for commercial vehicle chassis, wind turbine generator bearings, automated manufacturing conveyors, progressive feeder distribution banks, and heavy industrial machinery processing lanes.
