Product Description

Double Pilot Opreated Hydraulic Control Valve Hydraulic Lock for Crane

Introduction

A hydraulic lock, also known as a pilot-operated check valve, is an important component in hydraulic systems. It is used in various types of machinery, such as construction equipment, lifting machines, and mining equipment, to prevent unintended movement or to hold a load in place. Here's a detailed explanation of how it works and why it's used:

How It Works

1. Basic Structure: A hydraulic lock typically consists of a valve body with one or more check valves. These check valves are designed to allow fluid to flow in one direction while preventing backflow in the other.

2. Operation: When hydraulic fluid is pumped into the valve, it opens the check valve and allows fluid to flow to the desired location, such as a hydraulic cylinder that moves a load. When the pump is turned off or when pressure drops, the check valve closes, locking the fluid in place and preventing movement.

3. Pilot Operation: The hydraulic lock also includes a pilot pressure port. This feature allows for the opening of the check valve even when there's pressure on the downstream side, enabling controlled release or movement of the load.
