Equipment › Armature › Control valves › Ball valves
Each control ball valve is custom manufactured in accordnce with application requirements. Control valve can be 2-piece or 3-piece body construction. Stem seal manufactured for whole operating period. Seat design depends on operating conditions. Metal seated. Wide control range - over 500 : 1. Wide range of application: nitrogen, ammonia, petroleum liquids (petrol, diesel oils, fuel and bunker oils), acids (nitric, acetic, sulphuric, fatty, citric, hydrochloric), butane, water, steam, acetone, hydrogen, oxygen, natural gas and etc. Materials: carbon steel, CrMo low-alloy steel, austenitic stainless steel and others. Connection type: flanged, welded, clamp. Temperature up to +900 °С
Control valve operating principle In process of passage through valve’s ball a liquid the certain quantity of times changes movement direction.
Pressure up to 430 bar
DN 50-900
The right angle turns and expanding flow passageways removes the kinetic energy from the fluid, whilst lowering pressure in a controlled manner.
Pressure changes controlled at each stage. Stages quantity can reach 36.
