Rotary selector valve
The rotary selector valve is a rotary selector or distributor for use in pipe systems with small holes up to a pressure of 10 bar.
Roraty selector valve is a reliable unit, whose construction is based on a modular structure and it is possible to configure it for many applications. The Rotary selector valve body is rotatable and made of brass or stainless steel. It is characterized by extraordinary durability, because the spindles are made of stainless material, while the mandrels and seals are made of materials adapted to the conditions in which it will be used.
Each of the elements of the rotary selector valve is pneumatically independent. However, it is possible to simultaneously control separate air paths, because all the elements are connected by a common central spindle. Each output is a valve. The rotary selector valve may comprise an electric rotary switch. This allows simultaneous control of liquids and electrical circuits. It can also be used to remotely indicate the position in the control center. It is possible to control the cylinders pneumatically, which causes the valves to open or close. This happens when an electrical signal is sent from the control center to the remote solenoid valves. Instead, these valves increase pressure or ventilate the cylinders. This process is used in nuclear power plants that need high quality feed water to cool reactors.
Since the rotary selector valve was first put into use, it has been slightly modified. Currently, thanks to its versatility, it is used in many industries and is used to switch liquids, vapors and gases.
Positive Positioning is possible thanks to the indexing mechanism. It allows the operator to actually assess the position of the valves, thus eliminating leaving the valve in the middle position. Each valve may have its own internal spindle and each assembly may have its own configuration.
Rotary selector valve is equipped with a security system in the form of a valve blocking lock, explosion-proof switches and blocking of handles. The device housing is resistant to weather conditions. An important element of the rotary selector valve is the ability to switch liquids and gases simultaneously.
The Rotary selector valve is used in automated production plants where manual bypass is required in critical situations from a safety point of view. RSV is widely used in hostile environments such as offshore platforms.
