Which Valve is Used to Reduce Pressure?

 

Introduction

A pressure reducing valve (PRV) is specifically designed to lower and regulate high inlet pressure to a safe and consistent output level. These valves are widely used in industrial, residential, and commercial applications to prevent pressure surges and protect equipment.

Types of Valves Used to Reduce Pressure

1. Direct-Acting Pressure Reducing Valve

  • Best for small systems & residential use

  • Simple design with quick response

  • Compact & cost-effective

2. Pilot-Operated Pressure Reducing Valve

  • Best for industrial & high-flow applications

  • Provides more accurate pressure control

  • Handles higher flow rates

3. Adjustable Pressure Reducing Valve

  • Best for custom pressure control

  • Allows manual pressure adjustments

  • Used in commercial and industrial settings

Check Valve (Non-Return Valve): Types, and Pricing

  Introduction A check valve , also known as a non-return valve (NRV) , is a mechanical device that allows fluid to flow in only one direction, preventing backflow. It is commonly used in pipelines, water supply systems, industrial processes, and pumps to maintain directional flow and prevent equipment damage due to reverse flow. Check Valve Symbol The check valve symbol used in engineering diagrams consists of a valve body with an arrow indicating the permitted flow direction and a barrier preventing reverse flow. It is commonly seen in process flow diagrams (PFDs) and piping and instrumentation diagrams (P&IDs). Types of Check Valves (Non-Return Valves) There are several types of check valves (NRVs) designed for specific applications: Swing Check Valve – Uses a hinged disc that swings open with forward flow and closes when the flow reverses. Dual Plate Check Valve – Features two spring-loaded plates that automatically open and close with the...
