The gate valve belongs to the category of pipeline shut -off equipment parallel type, with a locking element - a knife.
The main task of each manufacturer of the valves is the use of high-quality materials, reliability and quality during assembly and testing, clear rules for transporting, installation and operation of finished equipment.
gate valves Slaber, Spain is produced in Europe according to the standards EN, ISO9001, ISO 14001, which indicates the quality and environmental control of production. Absolutely all components of the valves, and of course, the valves themselves comply with EC 2014/68/UE
standards.The format of the use of gate valves is very diverse
- oil refineries and chemical production plants.
- Production and packing of bulk and fluid building materials (lime, cement, concrete solutions).
- utilities (reinforcement for storm drains, collector and sewage bouncers).
Given the multifunctionality of their use by manufacturers, adapted and modernized adapted to certain areas of activity of the slot model that meet the highest modern requirements for reliability and quality.
The principal diagram of the device
Despite the simplicity of its device gate valves relate to the category of locking equipment requiring compliance with certain norms and accuracy in manufacture. The principal diagram of the device of the classic model is as follows:
1) a knife
The most important part of the gate valves is a knife, since it directly interacts with the environment.
based on the design of the gate valve, as well as its fundamental purpose, the knife has a different shape:
- rounded;
- straight;
- through;
2) the case
the case, or as the people say, the “body” of the valve may differ both in its design and in the materials of the performance.
Structurally, the case is produced by whole cast or composite two or more parts. But in one or another version of the knife valves, the type of accession has: between flange or flange.
Materials of the case execution: cast iron GJS 250, GJS500, WCB steel, stainless steel CF8M, AISI316, DUPLEX, URANUS BC, etc.
Often, the gate valve housing has a fairly small building length, especially if the interflant type valve. This is a big plus both during installation and dismantling the valves.
