Rajeev & Company

We also manufacture Cutting Tools such as:

• Spot Face Cutters in custom sizes.
  

• U drills in custom sizes.

We undertake repairs of Ball Valves. Ball Valves usually do not function satisfactorily because of -

• Leakage
• Jams
• Handle breakage

The leakage of fluids in ball valves is mainly due to damaged seats and seals. The seats and seals can be replaced at a fraction of the cost of a new ball valve to make these valves work as new. Ball Valves get jammed when material flowing through it, gets solidified. This can also be repaired by dis- assembling and replacing the damaged parts. In some cases, due to continuous usage with corrosive media, the balls get damaged. These ball can be reconditioned and the valve works as new. Many customers prefer to get the old ball valves repaired rather than buying new ones to save on resources. We guarantee our repaired valves to work as satisfactorily as our new ball valves.

Automation of Ball Valves is done by using pneumatic or electrical actuators. The actuators are mounted on to the ball valves using special brackets and are controlled by 90 degree operation, to open or close the valve. It is important to choose the right kind of actuator, by knowing the torque required to operate the valve.

Gate Valves are controlled with continuous rotation of motors, rotating in opposite directions to close and open the valve. The upper and the lower limits of the Gate Valve are controlled by limit switches, which signals the motor to stop then the valve reaches the extremes. A control panel is used to control the time and interval of opening and closing of the valve. The control panel consists of indicator lamps, main switch, timers, contactors, MPCB etc and is programmed to operated as per customer's requirement. The Gate valve itself is modified to hold the limit switches and the motor and necessary brackets and mounting plates are provided to take care of this. There is also a provision to operate the valve manually, in case of emergency. The Automation is usually designed and executed as per customer's specific requirement.
