The quality of modern valves is quite high, which has a positive effect on the service life. By placing a factory-installed butterfly valve in your pipeline once, you will forget about valve problems for years to come.
Many types of pipelines today require specialized types of valves. Sometimes it is enough to install emergency valves and valves in combination with pressure regulating valves. But it is often required to complete the system with faster and lighter fittings .
One of these types of equipment is a butterfly valve. The use of high-quality valves solves the problem of quickly shutting off the flow of the working medium in the system in case of technological needs or simply stopping the supply of material.
Butterfly valve design and benefits
The use of this element of shut-off valves allows a much faster response to emergencies. Simple design complemented by high tightness and low risk of equipment failure .
The valve consists of a cast-iron body, a stainless or steel disc that blocks the flow of the working medium in the system, as well as a mechanism that drives the disc. The butterfly valve is one of the most compact pipeline fittings, which offers the following benefits:
- low weight of the structure, no load on the pipeline;
- compact size, which allows easy and quick installation of equipment;
- the minimum metal consumption of the structure becomes the reason for the low cost;
- easy operation with a lever handle.
The cast-iron valve can be installed in any position - the quality of the element's work does not depend on this . Long service life and easy maintenance are also important advantages. The equipment will serve well not only the warranty period, but many times longer.
Scope of application of closures
Today, such convenient equipment as a butterfly valve is used in many fields of activity where it is necessary to transport liquids or gases using pipes. The use of a valve with a stainless steel disc significantly increases the range of acceptable types of working environment , and also creates additional operating benefits:
- the maximum allowable temperature of the internal environment increases;
- the resource of the shutter service increases;
- often in such equipment all the components are made of a higher quality.
Cast iron valves with stainless steel disc are produced by European enterprises. Their cost is an order of magnitude higher than that of other manufacturers, but service life and the terms of the manufacturer's warranty will please the buyer to a greater extent .
When purchasing valves, you must make sure of their factory origin, which can be checked by the documentation and markings on the equipment body.
