  • Hydraulic Valve Remote Control System
    HYDRAULIC VALVE REMOTE CONTROL SYSTEM OVERVIEW Nordic Flow Control’s compact design for our Hydraulic Valve Remote Control Systems does not compromise on power. Our systems operate at a higher torque level even with our smaller actuators. Submerged applications are available, and maintenance is possible even during operation. By having a hand pump in a deck box with solenoid valves, manual operations are now possible. Our Hydraulic Valve Remote Control Systems are tried and tested in the harshest conditions. The system consists of the hydraulic actuator, a power unit, solenoid valve cabinet, and the control station with operating system. Our actuators and control systems are able to match and operate valves with no limitations. BENEFITS • Able to operate bigger size valves with smaller actuators • Able to use for submerged applications • Cost efficient • Reliable • Able to operate at hazardous areas • Simplicity of design and control Nordic Flow Control Valve Remote Control Systems 1 COMPONENTS ACTUATORS Nordic Flow Control’s actuators are manufactured using sophisticated machinery in our own production plant. They convert hydraulic energy directly into a mechanical rotating movement by using the rack and pinion principle, elimi- nating cost from intensive servicing, maintenance and the sensitivity of transmission elements. Our actuators are created for durability, performance and cost effectiveness. Our new NRA series actuators are now more compact and provide higher torque at even smaller sizes. They have a longer life span, with higher efficiency. Polymer bearings for smaller actuators and ball bearings for bigger actuators are used to reduce friction between the parts. Mounting is according to ISO5211 standards, but can be customised to meet other requirements.

  • ERHARD Needle Valves Needle Valves – for Safe and Exact Control
    ERHARD is a company of ERHARD needle valves Needle valves – for safe and exact control Needle valves are the suitable valve to use whenever pressure heads or flow rates need to be safely and reliably reduced and controlled. They are used for two main tasks: • By restricting the cross-section, a change in flow rate, flow velocity and pressure is forced, which results to higher stress in the valve. The valve must therefore be designed so that potential cavitation cannot cause any damage whatsoever. • To be able to control the pressure and flow precisely and finely, the control valve’s control characteristics must be as linear as possible over the whole opening range. Thanks to their well thought out design, ERHARD needle valves fulfil these requirements to the greatest possible degree and are therefore the ideal valve for numerous control tasks. Because even if butterfly valves and gate valves All the components of the ERHARD RKV are used for such tasks in individual cases in practice, due to their design as needle valves are designed on the basis of an optimum shut-off device for “OPEN/CLOSED” operation, but they are not decades of experience. At the same time, suitable for continuous use as a control valve. state of the art techniques are used in the development, e. g. the finite elements methods (FEM).

  • 1 and Butterfly Valves
    PIPING INSTRUMENTS-II Introduction Valves are used to isolate equipment and piping devices, regulate flow, prevent backflow, regulate and relieve pressure. They are critical components of piping systems so that they must be properly located, oriented and configured. Valves operated frequently need careful consideration. There are several kinds of valves: isolation, regulating and safety valves. Isolation valves are used to turn on or turn off fluid flow. Examples are gate, ball, and plug valves; the gate valve is probably the most popular. Knife valves are similar to gate valves but occupy smaller space, weigh less and cost less. Regulating valves are used to control flow direction, rate and pressure. Flow rate valves include globe, butterfly, needle and diaphram. The globe valve is very popular and may be found in lines up to 12” diameter. It has a relatively high pressure drop. The butterfly valve is good for low-pressure lines and offer minimum pressure drop. The needle valve has a needle-like stem with fine threads that allows it to be used for accurate throttling. The diaphram valve is common in the food and beverage industries. Pressure control valves are more often called pressure regulators. Check valves e.g. lift or swing valves prevent back flows and thus protect upstream equipment and personnel. Safety valves are used to limit operating pressures and temperatures. They open at set pressure or temperature values and prevent damage to equipment and personnel. Examples are pop and relief valves. Pop valves are used for air, gas, and steam lines and open at set values. Relief valves are used for liquids and open and close more slowly.

Olin(1) Abstract Capillary tube thermal mass flow meters directly measure the mass flow rate of clean gases and gas mixtures in lower flow ranges. A capillary tube thermal mass flow controller adds an integrally mounted flow control valve to the flow body of the mass flow meter and both monitors the mass flow rate and controls it to be equal to a set-point value selected by the user. This paper describes capillary tube mass flow meters and controllers for use in general purpose industrial and laboratory applications and in the fabrication of semiconductor devices. It provides a detailed description of the major components-- -flow body, flow conditioner, bypass, capillary sensor tube, control valve, and electronics. Flow ranges and specifications for which this technology is best suited are presented. The paper explains the principle of operation; describes gas conversion factors that provide Fig.

  • Dome-Loaded Back Pressure Regulator Improves Mass Flow Controller Calibration Process
    Dome‐loaded Back Pressure Regulator improves Mass Flow Controller calibration process by Jeff Jennings, PE Thermal mass flow meters and mass flow controllers are widely used throughout laboratories and industry in situations requiring precise control of gas flow rate.. As shown in the Figure 2, mass flow controllers are often used to supply inert and other gases into laboratory reactors and vessels. Fig 1: Thermal mass flow controller In order to calibrate these devices precisely, it is accepted good practice to showing flow control valve on outlet control the outlet pressure of the devices in the same range as the application pressure. This article describes how a sensitive dome‐loaded back pressure regulator can improve the quality and efficiency of the MFC and MFM calibration process. Thermal mass flow meters Thermal mass flow meters (MFM’s) are the dominant method Fig. 2: Mass flow controllers supplying multiple gases into of measuring gas flow in laboratory and small scale a research reactor. The back pressure regulator is used applications. MFMs sense mass flow by measuring the to control the overall reaction pressure. amount of heat transferred by the gas flow in a thin hot tube in the gas stream. They can use either a constant temperature method (variable power input), or a constant power method (variable temperature). For all but the smallest MFMs, the flow sensor is situated in a small side stream of the overall stream flow, and a laminar flow divider is typically used to provide reliable scaling from the small side‐stream flow sensor to the overall flow meter stream (see Fig.
