Q641F/H/Y Pneumatic O-type Shut-off Ball Valve product details

Q641F/H/Y Pneumatic O-type Shut-off Ball Valve summary
Q641F/H/Y Pneumatic O-type Shut-off Ball Valve produced and sold by Baigang valve group pneumatic actuators using new AT/GT series pneumatic actuators, double and single action type (spring return), the use of rack and pinion structure transmission, performance more safe and reliable.
 
Q641F/H/Y Pneumatic O-type Shut-off Ball Valve Introduction

Pneumatic O-cut off ball valve pneumatic actuators using new AT/GT series pneumatic actuators, double acting and single acting type (spring return), the use of rack and pinion structure transmission, performance is more safe and reliable;AW series pneumatic actuators are adopted for large caliber valves, with fork structure transmission, reasonable structure and large output torque.
Pneumatic O-cut off ball valve with one second time to cut off the ball valve, with explosion-proof device, can be cut off by gas.It is composed of ball valve and single acting piston pneumatic actuators, widely used in natural gas, oil products, chemical, metallurgy, papermaking, electricity office, mining, printing and dyeing, biological pharmaceutical, daily chemical industry, food and beverage, water treatment and air treatment and other industries of fluid cut-off control, and automatic pneumatic instrument matching use.
 
Q641F/H/Y Pneumatic O-type Shut-off Ball Valve works
 Pneumatic O-cut ball valve by the body, ball, valve shaft, seal ring, packing, platen and other components. Actuators from the gas, piston, gear type, output shaft, cylinder head, bearings, guide ring, piston bush, adjusting bolts, "O" ring and other major components. Actuator and valve connection shaft. Cylinder input pressure, the role of the piston to produce a certain thrust, the gear-type output driven by the piston, the gear output shaft in rotation, driven by the rotation of the valve shaft, so that the valve ball with the rotation of the valve, change the valve Flow area, to achieve the purpose of changing the medium flow through the valve. 
 
Q641F/H/Y Pneumatic O-type Shut-off Ball Valve Features
 1, thrust bearing to reduce stem friction torque, stem long-term operation can be smooth and flexible. 
 2, seat sealing performance, using PTFE and other elastic materials made of seals.
 3, anti-static function: In the sphere, the valve stem, the spring between the body, the process can switch the static electricity derived. 
 4, the stem seal is reliable, as the stem only for rotational movement without lifting movements, stem packing seal is not easy to damage. 
 5, due to PTFE and other materials with good self-lubricating, and friction loss of the ball is small, so the long service life of the ball valve. 
 6, cut off fast, with one second cut off capacity, and good sealing performance, explosion-proof device can be equipped with gas pipe can be cut off.
