Description
Actuated Flush Bottom Ball Valves are designed with bent or angular bonnet to get clearance in bottom of machine. As named Flush Bottom Valve, the valve has application of flushing the liquid in tank. For automation Pneumatic rotary actuators are installed to automate the Flush Bottom Ball Valve. This Actuator are pneumatic and can be single acting or double acting with or without accesories as per requirement. Liquid can be drained off remotely and with minimum labor.
Features and Specialities
• Automate liquid drain operation, minimize the labor.
• Automation accessories such as solenoid, limit switches, positioner offer as option. Precise control over important process parameters.
• Available with Anti corrosive Teflon lining for pharmaceutical and chemical application.
• Valves available in BS, ANSI, DIN, standards.
• Manual override provided for safety and emergency.

Description
The jacket covers the body from one flange to the other flange. The body is modified by adding oversize flanges. As example: 2" x 3" Jacketed Ball Valve has the nominal bore of 2" (DN 50) and the flange size is 3"(DN 80). It allows enough space for bolting clearance. The Jackets assure consistent valve Heating or Cooling of the process media to prevent crystallization or seizing of flow media. The Jacketed Ball Valve (Heating Jacket Ball Valve) with very well design to help the high temperature steam or oil flow over the valve ball & body parts to keep the media liquid. In addition, the efficient flow of media is ensured through the elimination of pockets. Steam, can be used as carrier for heating media. Following quality assurance rules, every valve is tested again after the Jackets have been welded (Fabricated) to the body. Jacket Hydraulic & Air Test is carried out at 6.0 Kg. /Cm2. 

Generally standard Jacketed Ball Valves are delivered in carbon steel and different types of stainless steel materials. Other special materials are available upon special request. These Jacketed P.T.F.E. seated Ball Valves gives Zero Leakage, Tight Shut-Off and Low Torque with easy smooth operation at temperature ranging from -20° C. to +220° C. Electro-Polished, Buff Finish & Ultra clean valve also provided for Food & Pharmaceutical Industries on request.

The jacket covers the body from one end to the other end. The Jackets assure consistent valve Heating or Cooling of the process media to prevent crystallization or seizing of flow media. The Jacketed Non Return Valve (Heating Jacket Non Return Valve) with very well design to help the high temperature steam or oil flow over the seating & body parts to keep the media liquid. In addition, the efficient flow of media is ensured through the elimination of pockets. Steam, can be used as carrier for heating media. Following quality assurance rules, every valve is tested again after the Jackets have been welded (Fabricated) to the body. Jacket Hydraulic & Air Test is carried out at 6.0 Kg. /Cm2. Generally standard Jacketed None Return Valves are delivered in different types of stainless steel materials. Other special materials are available upon special request. These Jacketed Non Return Valves give class IV Shut-Off for metal fitted valve & class VI Shut-Off zero Leakage in soft sitted arrangement. EPDM / White on / Nitride as per client requirment, Tight Shut-Off and Low Torque with easy smooth operation at temperature ranging from -20° C. to +220° C. Electro-Polished, Buff Finish & Ultra clean valve also provided for Food & Pharmaceutical Industries on request.

Description  
Ambika has designed spring-assisted check valve (Sanitary NRV) for horizontal mounting to prevent flow reversal in industries. In horizontal NRV the line of flow is eccentric for the flow output and because of this the fluid flowing through the NRV does not stay at seat due to gravitation force. This help for better operation in horizontal mounting as well less effect of back pressure in valve. The conventional NRVs are in same line of flow which do not have this feature. The specially designed end connection is easy for mounting and dismounting and so it is comfortable for maintenance and less time consuming. Additionally body and seat, is fastened with a quick release clamp and elastomeric body seal to permit fast and easy access to the internals.

Description
       Ambika has designed spring-assisted check valve (Sanitary NRV) for Vertical mounting to prevent flow reversal in industries. The internal surface finish is 0.8 Ra while the disc and seat are lapped to provide excellent shutoff. The specially designed end connection is easy for mounting and dismounting and so it is comfortable for maintenance and less time consuming. Additionally body and seat, is fastened with a quick release clamp and elastomeric body seal to permit fast and easy access to the internals.
Principle of operation
  In line spring assisted NRV is designed to prevent reversal of flow with strict clean condition. The valve opens whenever the pressure below the plug exceeds the pressure above the plug due to spring and higher counter pressure will press the plunger valve against the seat to close the valve.
