German Hosco valves Hosco models Hosco prices

Hosco valves consist of two main assemblies: the valve body assembly and the actuator assembly (or actuator system). They are divided into four major series: single-seat control valves, double-seat control valves, cage-style control valves, and self-operated control valves. Variants of these four valve types can result in numerous different applicable structures, each with its specific applications, features, advantages, and disadvantages. Although some control valves have a wider range of operating conditions than others, control valves are not suitable for all conditions, to jointly build the optimal solution for enhanced performance and reduced cost. Valves Hosco valve types

There are many types of control valve bodies, commonly including straight-through single-seat, straight-through double-seat, angle, diaphragm, low-flow, three-way, eccentric rotary, butterfly, cage-style, and ball. For specific selection, consider the following: 1) Primarily consider factors such as the selected flow characteristics and unbalanced forces. 2) When the fluid medium is a suspension containing high concentrations of abrasive particles, the internal materials of the valve must be hard. 3) Due to the corrosive nature of the medium, choose valves with simple structures whenever possible. 4) When the temperature and pressure of the medium are high and fluctuate significantly, select valves whose plug and seat materials are less affected by temperature and pressure changes. 5) Flashing and cavitation occur only in liquid media. In actual production processes, flashing and cavitation cause vibration and noise, shortening valve service life; therefore, prevent flashing and cavitation when selecting valves.

Hosco valve features

1) Control valves come in various types with different applicable scenarios; therefore, select the control valve type reasonably based on process production requirements. 2) Pneumatic control valves are classified as air-to-open and air-to-close. Air-to-open control valves close in a fault state, while air-to-close control valves open in a fault state. Auxiliary devices can be used to form a lock-up valve or enable the control valve to self-lock, meaning the control valve maintains its pre-fault opening position during a fault. 3) Air-to-open and air-to-close modes can be achieved through combinations of direct-acting and reverse-acting actuators with direct-body and reverse-body valves. When using a valve positioner, these modes can also be implemented via the valve positioner. 4) Various control valve structures differ and each has its own characteristics.

Hosco valve selection and application

Control valves are actuators in automatic control systems, and their application quality directly reflects the regulation quality of the system. As terminal elements in process control, people have updated their understanding of their importance compared to the past. The effectiveness of control valve application depends not only on product quality and correct installation, use, and maintenance by the user, but also on correct calculation and selection. Errors in calculation and selection can cause the system to start and stop frequently, or even prevent commissioning. Therefore, users and system designers must recognize the importance of valves in the field and pay sufficient attention to control valve selection. Hydraulic water level control valves automatically open and close pipelines to control water levels. They are suitable for automatic water supply systems in various water towers (tanks) in industrial and mining enterprises and civil buildings, and can serve as circulation water supply control valves for atmospheric boilers. This valve is compact, easy to install, highly sensitive in activation, has low head loss, and produces no water hammer. Controlled by a small float ball, it significantly improves water tower utilization. For new water towers, the reduced volume of the float ball decreases the height required for free floating at the top of the tower, lowering construction costs. It overcomes the drawbacks of old-style lever float valves, such as large size, susceptibility to damage, low working pressure, and excessive overflow, making it a suitable product for new water towers and for replacing old-style float valves.
