Specifications:
The document details ball valves with a pressure specification of 16 bar. The valves are designed for manual shut-off of gases, air, water, and light/heavy fuel oil, compliant with DVGW code G 260 and DIN EN 437. Operating temperature ranges from -20°C to +60°C.

Dimensions and Weight:
The document provides a table listing various models (KH-F 015 to KH-F 250) with their respective dimensions (BL, H, R in mm) and weights (kg).

Construction:
- Housing: DN 15 - DN 20 made of steel, DN 25 - DN 250 made of GGG 40.
- Ball: Chromium-plated, with materials varying from brass to stainless steel depending on the size.
- Spindle: Chromium-plated, made of brass or steel.
- Seals: Ball seal made of PTFE, spindle and housing seals made of Viton.
- Flanged connections conform to DIN EN 1092.

Certifications:
The valves comply with the Pressure Equipment Directive 2014/68/EU for sizes greater than DN 25 and are certified by DVGW.

General Information:
The KH-F...HTB models meet the GT 5 requirements for higher thermal resistance, capable of withstanding 650°C for 30 minutes. Note that DN 250 has a reduced passage to DN 200.
