Gas Ball Valves

Gas Ball ValvesExforma has designed and manufactured gas ball valves since 1991. Exforma's gas valves twice won the competition "Top-100 goods of Russia" - in 2004 and 2012.

The undeniable advantage of gas valves GSHK of Exforma production is the applying of a thick-walled aluminium tube for manufacturing the ball gate. Gas valve body is manufactured by hot forging which makes

them more reliable than welded ones. A secret of such reliabilities is in the applying of MAO technology to the ball gate surface. Due to the perfect geometry of the ball surface and full bore gate the valve provides minimal aerodynamic and hydraulic resistance.

Screwed ball valves when installing use standard fittings and boxes and hermitization by FUM tape or tow with iron minium.

Flanged ball valve with floating flange provides installation in any position and do not require theta alignment of flange mounting bores .

Electric Single-Turn Actuators is designed to actuate and move the different regulatory bodies: shut-down valves, dampers, seals, gate valve, cutoff valve, etc in automatic control systems in accordance with command regulators systems which are submitted to regulation law or control devices or under operator's command in a manual mode.
