Product Specifications

Technical details and manufacturing context for Pressure Regulator

Definition
Within an Industrial System, the Pressure Regulator is a critical control component that ensures downstream equipment receives stable, predetermined pressure levels. It protects sensitive instruments, optimizes process efficiency, and prevents damage from pressure surges by automatically adjusting its internal mechanism to compensate for upstream fluctuations. This product is a component used in machinery and equipment manufacturing, typically installed in pipelines to manage fluid pressure. It is available in materials such as stainless steel and brass, with a nominal diameter range of 15–100 mm (ISO 6708). The set pressure range is adjustable from 0.05 to 1.0 MPa, with an accuracy of ±5% of set pressure. The maximum inlet pressure is 1.6 MPa, and the operating temperature range is -20 to 80 °C. Flow capacity (Cv) ranges from 0.5 to 15, and the leakage rate is ≤0.05% of set flow (ISO 5208). The material grade is CF8M/316L (ASTM A351), and weight varies from 2.5 to 25 kg depending on size and material. These values are reference ranges for directory purposes; actual specifications must be confirmed with the legal manufacturer or supplier for the specific model and application. The regulator operates by balancing forces within a sealed chamber, using a diaphragm or piston against an adjustable spring. It is essential to verify model-specific values and standards before procurement or installation.
Working Principle
The Pressure Regulator physically functions by balancing forces within a sealed chamber. Incoming fluid pressure acts on a diaphragm or piston against the force of an adjustable spring. When output pressure drops below the setpoint, the spring force overcomes the diaphragm, opening a valve to allow more flow and increase pressure. When output pressure exceeds the setpoint, the diaphragm compresses the spring, closing the valve to reduce flow and lower pressure, maintaining equilibrium.

Reliability & Engineering Risk Analysis

Failure Mode & Root Cause
Diaphragm rupture
Cause: Fatigue from cyclic pressure loading or chemical degradation from incompatible process media
Seat wear/erosion
Cause: Particulate contamination in the fluid stream causing abrasive wear or cavitation damage from high pressure differentials
Maintenance Indicators
  • Pressure fluctuations or inability to maintain setpoint (audible: chattering/hissing)
  • Visible external leakage around bonnet or downstream connections
Engineering Tips
  • Install upstream filtration (10-25 micron) and maintain clean, dry instrument air/gas to prevent contamination damage
  • Implement regular calibration checks and verify proper pressure differentials to avoid cavitation conditions
