VAA-B Angle Relief Valve – Balanced Stem
DESCRIPTION
The design of this relief valve ensures that the breakdown pressure is only sensitive to the inlet pressure and not affected by the outlet pressure.
CHARACTERISTICS
• External adjustment without disassembly the valve.
• External range engraving.
• Lock wire feature secures a given pressure setting.
• Reliable retention of the sealing o'ring.
• “Dry” spring, fluid does not touch it.
• With ultra-hard plated and mirror finish for minimum friction.
• 100% tested and calibrated in factory.
