Flush Bottom Valve
Flush Bottom Valves are used in piping, reactors & vessels to drain out Liquids, Abrasive, Slurry, Viscous Material or Semi Solid Media. Flush Bottom Valves are Available in design of Disc opening into the Tank (Vessel Opening Design) & Disc Lowering (Inside Valve Opening Design) into the Valve Body. Flush Bottom Valves with disc opening into the tank or opening upwards is the most commonly used. It is used where enough space is available between Bottom pad and the stirrer of the tank. The mass load inside the tank helps closing & tight shut off the Flush Bottom Valve. Normally,the inlet size of a standard flush bottom valve is one size higher than that of the outlet size. There are special construction possible with both sizes same. The outlet port is at an angle to the inlet port.Normally 45 or 60 degree deviation is provided. The end connection are normally flanged.

Upstream Pressure Regulating Valve
INSTALLATION AND MAINTENANCE AND OPERATING MANUAL FOR SELF ACTUATING PRESSURE REGULATING VALVE (SERIES – 725) GENERAL : This manual describes the instructions for handling, storage,installation, maintenance, and operation of the For self actuating PRV with spring opposed pneumatic diaphragm actuator. Instructions not detailed in this document shall be performed in accordance with standard and safe acceptable practices as may be required by local codes, specifications and or regulations. The instruction contained within this manual must be read before undertaking any work on the equipment supplied and if there are any questions please contact Pneucon Valves Pvt. Ltd. or its agent. When ordering any spares please specify the unique valve serial number detailed on the equipment nameplate.
Downstream Pressure Regulating Valve
Downstream Pressure Regulating Valve is self contained, self Operated control device, which automatically reduce a higher inlet pressure to a steady lower downstream pressure regardless of changing flow rate and varying inlet pressure. It utilizes energy from the controlled system. The regulator operates on the simple principal of force balance. A Downward opening force is exerted by the actuator spring, which is balanced by the upward force exerted by the controlled outlet pressure acting below the diaphragm. Any drop in controlled outlet Pressure due to consumption of Fluid, disturbs the force balance and due to spring force diaphragm and stem move down pushing the valve plug away from seat. This results in the increased flow. The pressure reducing regulators are manufactured in a variety to manage downstream system pressures in low, medium, high flow application; model features a diaphragm/Piston type or combination of both to suit different applications. These regulators find applications throughout many industries including the Oil & Gas, Pulp & Paper, Power Generation and chemicals processing industries etc.
Specifications
Features

Desuperheater
BUILT IN RELIABILITY PVCT-800 Desuperheater is a device that reduces the temperature of superheated steam so that it can be used effectively for heating or for other industrial use. This temperature reduction or attemperation is performed by desuperheater, which is essentially a device that injects a predetermined amount of water into a steam flow stream. The desuperheaters are highly effective in controlling steam temperature close to saturation point over a broad set of steam conditions The desuperheater provide effective heat transfer between steam and water. A highly effective desuperheater design and application ensures that costly problems are avoided including extended startup and shutdown times, reduced process efficiency and general wear of downstream piping and equipment. Pneucon incorporate latest technology in the spray nozzle design. The high quality surface finish minimises frictional losses, thereby ensuring that the total pressure difference between water and steam is available for atomisation of water.
