AP100 Series Compact Pressure Relief Valve

Brand: SOLH by Richge Technology (睿其格科技)

Product Positioning

     AP100 series is a direct-acting spring compact relief valve for miniature pneumatic circuits. It automatically exhausts excess air to stabilize system pressure once pressure exceeds preset value. Featuring mini size and easy pressure tuning, it serves as overpressure protection and upper-limit pressure control component for compact pneumatic equipment.

Structure & Working Principle

     --Structure: Direct acting spring return relief design without pilot control

     --Working logic Closed state: System pressure lower than set value Open state: System pressure reaches or exceeds set value, air exhausts to ambient Reset state: Valve re-closes when pressure falls below preset threshold

     --Simple mechanical assembly composed of adjustment knob, spring and spool

     --Reminder: Not certified as JIS standard safety valve, only for pressure regulation and circuit overpressure control

Core Key Features

1. Ultra-Compact Lightweight Single Unit

     Overall dimension 69×40mm, net weight merely 0.12kg. Independent single-body design supports direct installation, perfectly suited for narrow and embedded equipment layouts.

2. Lockable Tool-Free Adjustment Knob

     Blue top knob realizes direct pressure setting without extra tools. Locking structure prevents unintended pressure shift caused by vibration or misoperation for stable long-term operation.

3. Dual Adjustable Pressure Ranges & High Relief Flow

     Standard model adjustable range: 0.05–0.69MPa Low-pressure X201 version: 0.02–0.2MPa Maximum allowable working pressure hits 1.0MPa; large internal flow channel ensures rapid pressure release.

4. Diversified Thread Options & Flexible Mounting

     Available port sizes: 1/8"(01), 1/4"(02) Customizable thread standards: Rc, NPT, G thread Two installation ways: direct threaded mounting or bracket fixing Clear IN/OUT marking ensures unidirectional air flow installation.

5. Corrosion Resistant & Stable Long Service Life

     Die-cast aluminum alloy valve body with wide temperature tolerance from -5℃ to +60℃. Designed for dry compressed air, lubrication-free operation lowers maintenance cost.
