Water Pressure Regulator Valve

 

Introduction

A water pressure regulator valve (PRV) is designed to control and stabilize water pressure in plumbing systems. It prevents excessive pressure that can damage pipes, fixtures, and appliances. These valves are commonly used in residential, commercial, and industrial water supply systems.



How Does a Water Pressure Regulator Valve Work?

  • Reduces high inlet pressure to a safe and steady level.

  • Uses an adjustable spring and diaphragm to regulate flow.

  • Protects pipes, faucets, and appliances from pressure damage.

  • Enhances water conservation and efficiency.

Types of Water Pressure Regulator Valves

1. Direct-Acting Pressure Regulator

  • Best for small-scale residential applications

  • Simple design with fast response

  • Affordable and compact

2. Pilot-Operated Pressure Regulator

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...
