The Difference Between A Lug and Wafer Butterfly Valve
2019-02-12 16:59:28
Butterfly valves have been around for a long time, and are used for a variety of applications. They made their first appearance during the 1930s, and have been utilized by several industries ever since. Often made out of cast iron, butterfly valve's name is based from the functionality of its disc.
Wafer type butterfly valve installation instructions and steps
2019-01-03 16:27:13
The wafer butterfly valve is one of the most common types of valves in industrial pipelines. The structure of wafer butterfly valve itself is relatively small. It is only necessary to put the butterfly valve in the middle of the flange at both ends of the pipe, and use the stud bolt to pass through the pipe flange and the pair.

- Product Details
RKSfluid Hydraulic Control Valves are designed to regulate pressure, flow, water level and other operating conditions in water supply, distribution and treatment systems. The product range includes pressure reducing valves, pressure sustaining and relief valves, flow control valves, level control valves, solenoid control valves, surge anticipation valves and pump control valves.
These pilot-operated valves use hydraulic pressure and pilot circuits to control the opening and closing of the main valve in response to system conditions or preset control requirements. Depending on the selected model, functions may include downstream pressure regulation, flow limitation, reservoir level control, upstream pressure maintenance and pump start-stop surge management.
Available configurations cover different nominal sizes, pressure ratings, body materials, sealing materials and connection standards. RKSfluid can help project buyers and distributors identify a suitable valve type based on the required control function, pipeline parameters and operating conditions.
Key Features
- Multiple Control Functions: Pressure, flow, level, solenoid, pressure sustaining and pump control options for water systems.
- Pilot-Operated Control: Pilot circuits regulate the main valve in response to hydraulic conditions or preset settings.
- Multiple Flow Configurations: Full-bore, reduced-bore and anti-cavitation configurations are available within the product range.
- Material Options: Ductile iron, stainless steel, duplex and other material options are available for selected models and sizes.
- Flexible Pressure Ratings: Configurations are available for different pressure classes and regional pipeline standards.
- Application-Specific Solutions: Valve selection can be based on water distribution, pressure management, flow regulation, reservoir level control and pumping-system requirements.

FAQs
Start with the required control function, such as pressure reduction, flow limitation, pressure sustaining or reservoir level control. Then define the flow range, inlet and outlet pressures, pipe size and pressure rating to identify the appropriate valve configuration.
A pressure reducing valve regulates downstream pressure, while a pressure sustaining valve maintains a minimum upstream pressure by restricting flow or opening when the upstream pressure reaches its setting.
A flow control valve limits the flow rate to a preset value, helping prevent excessive flow when line pressure changes. The required flow rate and available differential pressure are key selection inputs.
A level control valve uses a level-sensing pilot or float arrangement to control filling according to the preset water level. The appropriate configuration depends on the required level-control logic and installation arrangement.
A solenoid control valve is suitable when electrical signals are required to initiate opening or closing. Control voltage, normally open or normally closed operation, and integration with the control system should be defined in the specification.
Pump stations may require pump control, reverse-flow prevention, pressure regulation or surge management. The appropriate valve depends on the pump operating sequence, pipeline profile and expected pressure transients.
Full-bore and reduced-bore configurations provide different flow-passage options. An anti-cavitation device is intended to manage cavitation risk under suitable operating conditions. Selection should be based on flow, pressure differential and the required valve configuration.
Specify the required control function, nominal size, flow range, inlet and outlet pressures, pressure rating, medium, operating temperature, connection standard, control requirements and installation conditions. A system schematic or operating sequence is useful for complex applications.
