Flanged shut-off valve ARI-Stobu 35.006 DN20 (stuffing box)

Flanged shut-off valve ARI-Stobu 35.006 DN20 (stuffing box)

Designed for use as shut-off valves in industrial pipelines, including steam systems, energy, chemical industries, etc. The execution of valve bodies made of various grades of cast iron and steel allows the use of Ari-Stobu shut-off valves in almost all types of working media with a temperature range from -60 ° C to +550 ° C and an operating pressure of up to 160 bar. Internal elements (stem, plug, seat) are made of hardened stainless steel, with the option of execution of copper alloys, which makes it possible to use valves for brines, antifreeze salts and sea water.

Main technical data:

1. Nominal diameters: DN 15 - 500 . Prices for DN125 and larger diameters are available on request.
2. Nominal pressure: 40 bar.
3. Maximum operating temperature: +450 ˚С.
4. Closure tightness class: 1 according to DIN 3230-3 (no leakage at all).
5. Mounting position: arbitrary.
6. Connection: flanged

Design features:

• The floating plug and the high quality seat finish ensure complete tightness of the closure.
• Valve made of hardened stainless steel.
• High quality pure graphite oil seal.
• Housing cover with heat dissipator.
• When leaving production, each valve is tested for tightness of the body and the valve.
