Component Specifications

Definition
A threaded mechanical component designed for precise calibration of pressure relief settings in sanitary valves, featuring hygienic design with smooth surfaces, crevice-free construction, and corrosion-resistant materials to prevent contamination in food, beverage, and pharmaceutical processing applications.
Working Principle
The adjustment screw modifies spring tension within the pressure relief valve mechanism. Turning the screw clockwise increases spring compression, raising the pressure threshold at which the valve opens. Counter-clockwise rotation decreases spring tension, lowering the opening pressure. This allows precise calibration of the relief pressure setting while maintaining hygienic integrity.
Materials
Stainless Steel 316L (AISI 316L) with electropolished finish, meeting FDA and EHEDG standards for food contact surfaces. Alternative: Titanium Grade 2 for highly corrosive environments.
Technical Parameters
  • Length 25 mm
  • Head Type Hex socket (Allen) 4 mm
  • Thread Type M6 x 1.0 metric fine thread
  • Pressure Range 0.5-10 bar adjustable
  • Surface Finish Ra ≤ 0.8 μm (electropolished)
  • Temperature Range -20°C to 150°C
Standards
ISO 2852, DIN 11851, 3-A Sanitary Standards 74-03

Frequently Asked Questions

How often should adjustment screws be recalibrated in sanitary pressure relief valves?

Recalibration is recommended every 6-12 months or after any system pressure changes, following ASME BPE guidelines for hygienic systems.

Can adjustment screws be replaced without removing the entire valve from the process line?

Yes, most sanitary pressure relief valves allow screw replacement during routine maintenance without full valve disassembly, minimizing downtime.

What cleaning methods are suitable for adjustment screws in hygienic applications?

CIP (Clean-in-Place) with food-grade detergents at temperatures up to 85°C, followed by SIP (Steam-in-Place) sterilization at 121°C for 20 minutes.

Can I contact factories directly?

Yes, each factory profile provides direct contact information.
