Miyawaki REC1 Direct Acting For Steam

Manufacturer: MIYAWAKI Inc.
Model: REC1

Features

Self acting pressure reducing valve for steam
Automatic valve that reduces the steam supply pressure to a defined set pressure.
The downstream side directly responds to pressure fluctuations on the upstream side, maintaining a continuous flow adjustment. This dynamic interaction ensures smooth pressure transitions throughout the system.No external energy required

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.

Compact and cost effective design
Can be installed in tight spaces thanks to its compact design (small/lightweight). Offers reliable operation, energy saving, and productivity improvement.

Superb durability
Most of materials are made from stainless steel, making it durable and corrosion-resistant.

Easy handling
Pressure can easily adjusted by the topside handle.

Typical applications

Suitable for F&B equipment, medical equipment, bio-related equipment, and other compact steam equipments.

Minimum differential pressure is 10% of the primary side. Adjustable flow rate ranges from 3 to 30 kg/h (6.6 to 66 lb/h). Lockup pressure reaches up to 0.03 MPa (4.4 psig). The offset hits 60% when pressure is 0.1 MPa (14.5 psig) or less, 0.07 MPa (10.2 psig) between 0.1 and 0.6 MPa (87 psig), and 0.1 MPa (14.5 psig) at 0.6 MPa (87 psig).
