GYR-50000 series,it compressed air-driven, can be open or shut totally only if the ball is brought along rotating to be 90°,by the stem in the body,with excellent cut-off stability,it's served for control of various liquid,gas,and slurry fluid.

◇ GYR-51100 series have an eccentric partial sphere plug type, have a sphere plug in throughway body, rotary center of plug isn’t concentric with the axis of rotation, reducing seat wear, long service life. small in volume, light weight, wide control range, high GY-value, excellent sealing, wide operating temperature range. it’s mainly served to situation that media with high viscosity, containing solids, or easy to felt.

◇ GYR-51200 have a concentric partial sphere plug type,plug with V type notch,to turning with the seat relatively to have shearing force to cut off fibriform material,preventing jammed. the valve has little flow resistance, high flow coefficient, with increased valve seat ring, adjustable sealed, and good sealing characteristics.It’s specially served to automatic control that media with fiber slurry, viscous particles.

◇ GYR-51300 have a concentric total sphere plug type, pneumatic O type shut-off ball valve is a rotation type of shut-off valve with 90°angle. tight closed, high GY-value, It’s specially served to control that media with fiber slurry, particle. and widely served to control of gas, liquid, steam.
