This is a highly reliable control valve model 48000, specifically designed for high-temperature and high-pressure applications that can withstand harsh conditions. It was developed primarily for controlling high-temperature and high-pressure steam, where there are concerns about cage deformation due to frequent thermal cycles and rapid temperature changes. The basic structure adopts a suspended cage design. By using a suspended cage structure, the seat ring is fixed directly to the body in a screw-in type. This makes the cage less susceptible to thermal effects, preventing leaks from the seat ring gasket caused by thermal cycles typically seen in standard retainer structures, as well as erosion of the gasket surface. **Features** - Highly reliable and capable of withstanding harsh conditions, specifically for high-temperature and high-pressure applications. - Suitable for applications beyond the range of models 21000, 41000, 21119HP, and 21119AHP (70119HP) control valves. - Applicable to gases other than high-temperature and high-pressure steam. *For more details, please refer to the PDF document or feel free to contact us.*

The air-operated diaphragm actuator and double-acting cylinder actuator are devices that serve as the source of driving force for operating control valves. They can be applied to all reciprocating valves manufactured by Nippon Dresser. The standard operating actuator of the "87/88 type air-operated diaphragm actuator" is designed so that when the operating air pressure exceeds the spring setting pressure, it applies pressure to the upper surface of the diaphragm, causing the actuator stem to descend. The "51 type double-acting cylinder actuator" is designed with a focus on control for use with control valves. It achieves high output and high rigidity while being compact and lightweight. *For more details, please refer to the PDF materials or feel free to contact us.

This product is a booster relay specifically designed to match well with control valves. It is used to increase the operating speed when the required operating speed of the control valve is particularly fast, or when the actuator capacity is large. When the difference between the signal pressure and output pressure is large (conditions requiring a significant change in opening), it results in a high flow rate, while a small difference (conditions requiring a minor change in opening) results in a low flow rate. This characteristic aims to achieve both a reduction in operating time and stability. 【Features】 ■ Has flow characteristics suitable for control valves ■ Employs a secondary pressure partition plate for stable secondary pressure detection ■ Built-in bypass valve for sensitivity adjustment ■ Filters are used on both the supply pressure side and the signal pressure side ■ Exposed bolts and nuts are made of stainless steel ■ Available in BR200 and BR400 models *For more details, please refer to the PDF document or feel free to contact us.
