Double Check Valve

Double Check Valve is technically two single check valve cast in adjacent sequence. A single check valve stops the backflow of liquid or gas, but little quantities liquid or gas have passed back along the piping before it closes.


Generally under negative pressure the water that briefly bypasses the first check valve and causes it to close is stopped from going any further by the second check valve which closes at the same time.


In theory two single check valves placed side by side in series anywhere lengthwise in a piping system will act jointly as a double check valve, but the farther they are placed more likely it is that something will act to stop them to work.


  •  Products by Material

APPLICATION OF DOUBLE CHECK VALVE

 


Steel Plants

Steel Plants

Steel Plants plays an important role as a technology in the working and performance of mechanical work.

Steel Plants are alike to hydraulic systems but these systems compressed air is used in place of hydraulic fluid.

A pneumatic system is a system that exploits compressed air by using it to transmit and control energy. Steel Plants are used widely in various industries. Usually Steel Plants rely on a constant supply of compressed air to make them work which is provided by an air compressor. The compressor intakes in air from the atmosphere and stores it in a high pressure tank named a receiver. This compressed air is then fed to the system through a series of piping and valves.

Air from the atmosphere is reduced in volume by compression which results in increasing its pressure. It is used as an operational medium normally at a pressure of 6 kg/sq mm to 8 kg/sqmm.In pneumatic systems, maximum force up to 50 kN can be achieved. Actuation is achieved by controls which can be manual, pneumatic or electrical actuation.

Double check valve usually are used for metering flow applications, predominantly if a steady, calibrated, low flow rate has to be sustained for some duration in Steel Plants. Double check valve provides very important function of accurately maintaining vital dynamics in Steel Plants.


Chemical Plant

Chemical Plant

Chemical Plant is a small-scale production engineering module facility designed to research and upgrade to the full-scale production of a product.

It helps in generation generate information about the performance of the system for use in design of larger facilities.

Chemical Plants are implemented to reduce the risk connected with construction of large process plants.

As Chemical Plant are considerably less costly to build than full-scale plants. The business need not put as much capital at risk on a venture that may be inefficient or unfeasible. Moreover, design changes can be made more economically at the pilot scale and anomalies in the process can be worked out before the large plant is constructed.

They deliver valuable data for the design of the full-scale plant. Technical data related to material properties, corrosiveness, reactions for instance, may be available, but it is difficult to predict the behaviour of a process of any complexity.

Engineering data available from other processes may be available, but this data cannot always be plainly applied to the process of interest. Engineers use data from the Chemical Plant to enhance their design of the production scale facility.

Chemical Plant price differs with every field and application. Cost determination involves how large and complicated is the process design.

Double check valve provides very important function of accurately maintaining vital dynamics in Chemical Plant.Double check valve usually are used for metering flow applications, predominantly if a steady, calibrated, low flow rate has to be sustained for some duration in Chemical Plant.


Oil Refineries

Oil Refineries

Oil Refineries plays an important role as a technology in the working and performance of mechanical work.

Oil Refineries are alike to hydraulic systems but these systems compressed air is used in place of hydraulic fluid.

A pneumatic system is a system that exploits compressed air by using it to transmit and control energy. Oil Refineries are used widely in various industries. Usually pneumatic systems rely on a constant supply of compressed air to make them work which is provided by an air compressor.
