Whether you need a knife gate valve, pinch valve or check valve for mining, or even an industrial application, our Isogate® and Delta Industrial™ slurry control valves provide ease of maintenance and maximum reliability.

Unlike many other high-pressure and heavy-duty knife gate valves, Delta Industrial™ valves provide bi-directional zero-leakage isolation and offer long-term performance with exceptional isolation results, protecting your people, plant and environment from process fluids.

Choose the Economical and Versatile Weir Design for General Use or for Tough Corrosive and Abrasive Services. Available with a wide range of manual and automatic actuators, these valves are available with weir style and straightway flow patterns. Sizes range from 1/2″ thru 3″ threaded or weld ends: and 1/2″ thru 12″ flanged ends.

Whether you need a knife gate valve, pinch valve or check valve for mining, or even an industrial application, our Isogate® and Delta Industrial™ slurry control valves provide ease of maintenance and maximum reliability.

The Weir type diaphragm valve’s design makes it particularly efficient for controlling flow rates, minimizing dead volume, and handling viscous fluids. Their ability to provide reliable sealing and easy maintenance makes them a preferred choice in several industries.

Weir Diaphragm Valves. 2. For operating temperatures above 1200F, the permissible working pressure decreases as shown by the chart on the facing page. To find the maximum working pressure at the higher temperatures, select the pressure from the table below for the desired size and valve material. Then, find the corresponding 3

These are weir type diaphragm valves that use hydraulic fluid like water or oil to close or open valves by exerting large force on the diaphragm. These valves are often used in lower-speed applications.

The Tru-Trol Enhanced Weir type Diaphragm Valve is designed for leak-proof control of abrasive and corrosive liquids, suspensions, slurries, and pulps, while at the same time providing laminar flow characteristics of Straight Through diaphragm valves.

A weir valve is a commonly used diaphragm valve. In a weir valve’s design, the diaphragm component presses the raised saddle or lip to create a sealing action. The elevated lip completely closes the diaphragm with reduced stress.

In this overview, we will explore the various types of weir valves, their working principles, applications, and benefits, helping engineers and specifiers make informed decisions when selecting the most appropriate weir valve for their industrial processes.
