Pressure reducing valve (for steam, for air / gas) RD-41 type pressure reducing valve (for steam)
A pressure reducing valve that is ideal for food / kitchen equipment, medical equipment, laundry equipment, and air conditioning equipment (humidification) that dislike rust.
For higher grade steam lines, the main body is made of stainless steel.
- Where to use
- Food machineryMedical equipmentLaundry equipment
Major features
- It is possible to secure a large flow rate (heat amount) required when starting up the equipment.
- The main body is made of bronze or stainless steel, and the main part is made of stainless steel, so clean steam can be supplied.
- The secondary pressure can be finely adjusted with the manual handle of the automatic locking mechanism.
- High durability with SUS316L bellows.
