Technical Specifications Breakdown
Valve Type – DBD
Direct operated pressure relief valve.
Unlike pilot-operated types, this valve controls pressure directly via a spring-loaded poppet system.
Adjustment Type – S
Screw adjustment with protective cap.
Nominal Size – 6
Size 6 – commonly used for modular subplate mounting or manifold blocks.
Mounting Type – P
Subplate mounting configuration.
Alternative Neck Marking – K
Indicates cartridge-style internal construction.
Pressure Rating – 100
Maximum adjustable pressure:
100 bar (approx. 1,450 PSI)
Physical Characteristics
• Mounted on subplate/manifold block
• Four mounting bolt holes
• Bottom or side port connections
• Compact industrial design
• Heavy-duty steel body
Adjustment Method
The hexagonal top section is used for pressure setting:
• Turn clockwise ? Increase relief pressure
• Turn counter-clockwise ? Decrease relief pressure
Always tighten locknut after adjustment.
Working Principle
This valve operates using:
• Spring-loaded poppet
• Direct pressure sensing
• Instant response to pressure rise
When system pressure exceeds set value, the valve opens and diverts flow to tank, protecting pumps, cylinders, and hoses.
Typical Applications
• Hydraulic power packs
• CNC machines
• Injection molding machines
• Marine hydraulic systems
• Industrial automation
• Hydraulic test benches
• Medium-pressure circuits
• Safety pilot valve applications
Industries Served
• Manufacturing plants
• Marine & offshore
• Oil & gas
• Construction equipment
• Heavy engineering
• Process industry
Usage Note
Since this valve is rated for 100 bar, it is ideal for:
• Medium-pressure control circuits
• Secondary protection circuits
• Pilot control stages in larger hydraulic systems
