Double-leaf valves

The double-leaf valves are stainless steel disc valves

Double-leaf valves or "Butterfly valves" are an economical option for locking valves installed in systems with automatic or manual control.

Why are the locking valves called disc valves?

This is due to the fact that this type of stainless steel reinforcement has a regulating or locking element in the form of a disk, rotates around the axis perpendicular at an angle to the flow direction of the working medium used.

At the same time, such devices can be called:

• rotary shutters;
• flaps;
• hermetic valves.

Due to their similarity of the shape of the shutter to a butterfly, in English-speaking countries they are called butterflyvalve.

The stainless steel disc valve is a short cylindrical body. A diverse working environment flows through it.

Due to the large clearance and low flow resistance, manually operated butterfly valves made of stainless steels AISI304, AISI316L, with inserts made of EPDM, silicone, Viton are used in food industries to regulate and block the flow of raw materials, finished products and cleaning solutions at various stages of the technological process.

The disc valves are equipped with multi-position handles (an option with a two-position steel handle is possible).

The valves are controlled not only manually, but also with the help of various types of pneumatic or electric drives. For example, air/spring and air/air pneumatic disc valves are mainly used in food processing enterprises to automate the flow control of liquids.

Pneumatic actuators can be equipped with control control heads.

Technical conditions of operation of disc valves:

Applications of double-leaf valves:

• Oil refining industry;
• Food industry;
• Pharmaceutical industry;
• Chemical industry.

As a flowing medium, water, steam, mineral oils, foodstuffs, liquids of the chemical and pharmaceutical industries, as well as viscous media that meet sanitary and hygienic standards are provided.
