Product Overview

This valve is usually installed in a row on the outer side wall at the bottom of the sedimentation tank to discharge the sand and dirt deposited at the tank bottom. It uses a diaphragm instead of a piston, which eliminates moving friction, making it more suitable for granular media such as mud and greatly extending the service life of the valve.

Main Features

• Constructed with stainless steel, offering excellent corrosion resistance and durability.
• Adopts diaphragm structure, no moving friction, suitable for mud and other granular media.
• Designed for easy installation, typically mounted in rows on sedimentation tank bottoms.
• Efficiently discharges sedimented sand and dirt at the tank bottom.
• Long service life due to its wear-resistant and friction-free design.

Working Principle

When the valve is activated (via fluid pressure), the diaphragm deforms to open the valve port. This allows sedimented sand, dirt, and mud at the bottom of the sedimentation tank to be discharged smoothly. When the pressure is released, the diaphragm resets to close the valve port, stopping the discharge. The diaphragm structure ensures no moving friction during operation, adapting well to granular media.

Structural Features

• Main body made of stainless steel, ensuring good corrosion resistance and structural strength.
• Equipped with a diaphragm as the core actuating component, replacing the traditional piston to avoid moving friction.
• Designed with a bottom-discharge structure, matching the installation requirement on sedimentation tank bottoms for efficient sludge discharge.
• Compact overall structure, facilitating row installation and later maintenance.
• Sealing parts optimized for granular media, preventing leakage caused by mud and sand accumulation.

Maintenance

• Check hydraulic oil level annually
• Test closing time every 6 months
• Inspect disc and seat for wear during system shutdowns
• Lubricate adjustment mechanism yearly
• Verify proper operation after system pressure changes
