Miyawaki - Pressure reducing valve - Direct Acting for steam - RE2
Pressure reducing valves (PRV) are designed for regulating the downstream pressure and maintaining it within certain acceptable limits.
Ideally, a PRV should provide a constant downstream pressure while delivering the required flow, i.e.
The PRV automatically adjusts the steam flow to meet the downstream system demand.
Depending on the model, MIYAWAKI’s pressure reducing valves are designed for steam, air, gases and liquids.
Operating principle
Changes in downstream pressure are sensed by the bellows, which expands or contracts depending on the pressure change.
The movement of the bellows will be directly transferred to the spring, which will open or close the main valve, thus keeping the downstream pressure at a certain level.
Suitable for small processes such as sewing, cleaning, food industry, dyeing industry, apparel industry, heating equipment, sterilizer, rubber vulcanizer, medical equipment, bio-related equipment.
Compact and lightweight design allows installation in tight spaces.
(Model RE2 is the world's smallest steam pressure reducing valve)

Features
Direct acting pressure reducing valve for steam
Automatic valve that reduces the steam supply pressure to a defined set pressure. Pressure fluctuations on upstream side are followed by the downstream side. No external energy required
Compact and cost effective design
It is smallest among MIYAWAKI's pressure reducing valves. Can be installed in tight spaces thanks to its compact design (small/lightweight). Offers reliable operation, energy saving, and productivity improvement.
Easy handling
Pressure can easily adjusted by the topside handle.
Easy maintenance
An easy in-line access ensures easy and fast maintenance.
Operating features of direct acting pressure reducing valves
Downstream pressure changes are detected in the detection chamber, and the degree of opening of the valve is directly adjusted to maintain the set pressure.
Superb durability
Thanks to adopt overstress prevent mechanism which is MIYAWAKI's unique mechanism, and micro bellows valve which is made from stainless steel, making it durable and corrosion-resistant.
Flexible installation
This product can be installed either horizontally or L-shaped.
One push blow mechanism
Our unique blow off mechanism makes it easy to remove scale.
Typical applications
Suitable for steam iron in textile and cleaning factory, small steam equipment, and other such applications.
