Sealco 3800 Inline Quick Release & Holding Valve
The Sealco 3800 is a compact and durable inline quick release and holding valve designed for heavy‑duty pneumatic and air‑brake systems. It combines pressure holding and quick exhaust functions to optimise air flow control - making it ideal for applications such as lift axles, spring brake circuits, gates and locking devices where controlled air release and retention are essential.
Key Features & Benefits
- Dual‑function design: Acts as both a pressure holding valve and a quick release valve, improving responsiveness and stability in pneumatic circuits.
- Inline mounting: Compact profile allows installation directly into air lines with minimal space usage.
- Fast venting: Vents pressure quickly at the valve rather than back toward the supply source - improving brake or suspension release performance.
- Pressure retention: The holding feature helps retain delivery pressure during small supply side fluctuations, preventing unwanted brake application or loss of function.
- Rugged construction: Built for long‑term performance in demanding truck, trailer and industrial environments.
Applications
The 3800 valve is ideal for:
- Lift axle and spring brake circuits where rapid air release and secure pressure holding are needed.
- Gate and locking devices where stable pressure must be maintained until exhaust is desired.
- Systems where rapid venting enhances brake or suspension performance and control.
Why Choose This Valve?
The Sealco 3800 offers reliable performance and versatility in pneumatic control systems by balancing quick exhaust capability with pressure retention. Its compact, inline design and proven Sealco build quality make it a strong choice for fleet maintenance workshops, heavy‑vehicle air‑brake systems and industrial pneumatics that require efficient, dependable air control.
