Piston valveseat tightness in a piston valve is obtained by a cylindrically shaped burnished piston, connected to a spindle, and operated by a hand wheel, which enables it to move through the inner diameter of two sealing rings. The two sealing rings are separated by a ported spacer. The bottom ring rests on a cast machined groove of the body and upper packing ring is being held and remained pressed by a bonnet on top. The bonnet rests on the top ring, when tightened evenly by the nut of the stud presses the spacer, which in turn presses the bottom ring. This is done by keeping the valve in closed position. Thus the mechanism is aligned compressed and ready for operation. When the piston is in the high position, that is, held by only the upper valve ring, (which also ensures tightness to the atmosphere), the valve is open. When the piston is lowered and is held in place by both the upper and lower valve ring (and thus ensuring seat tightness between the valve inlet and outlet ), the valve is closed . Because of the use of the sealing rings, the piston valve is considered a soft-seated, valve. The contact between the piston and rings (sealing effect ) is positively assured by means of the pressure exerted by stud bolts. Spring washers (belleville type), are fitted to compensate expansion due to temperature variations. application:- the valve finds its best application in tight shut off of steam. They are used in process line s containing many different fluids such as water, steam condensate & thermic fluid line. The valve also has numerous applications in the control of liquid and gases also.

With the assistance of our team of professionals, we are offering highly durable Combined Pressure Reducing Cum Desuperheating Valve to our esteemed clients. The offered combined pressure reducing valve is a single seated globe type valve that combines pressure & temperature reduction in one compact solution. The high pressure and high temperature steam which enters the main branch, is reduced in pressure and then water is injected immediately after pressure reduction.

Features:

• The high velocity and turbulent flow conditions data present immediately following the pressure reduction allow for rapid atomization and absorption of the spray water
• Reduction of noise level due to mist formation by water is an added advantage
• Both pressure reduction and temperature reduction are done in a single valve, making it extremely efficient, cost effective & compact
• Designed to suit almost all applications for accurate pressure & temperature control. Unique water mixing provides superior control and eliminates piping thermal line

The Inverted Bucket Steam Trap is simply an automatic valve that opens for condensate, air and Co2 and closes for steam and it efficiently perform that basic function for long periods of time making it more economical.

Inverted bucket steam trap operates on the difference in density between steam and water. Steam entering the inverted submerged bucket causes the bucket to float which when lifted closes the discharge value. Condensate entering the trap changes the bucket to a weight that sinks and opens the valve to discharge the condensate. But unlike other mechanical traps, air and carbon dioxide are vented continuously at steam temperature through a small hole provided in the stainless steel bucket.

The heat of Inverted bucket Steam Trap is its leverage system that multiplies the force provided by the bucket to open the valve against pressure. There are no fixed pivots to create friction. It is designed to open the discharge for maximum capacity. Wearing point are reinforced for longer life. Valve and Seat are made of heat treated chrome steel. The use of different leverage ratio for each orifice size makes it possible to open the maximum size orifice at any given pressure. Each size of Inverted Bucket Steam Trap is available with different sizes of pressure changes Assemblies at different pressure intervals so that the capacity of any one size is maintained at its optimum level.

Three way valve which design for diverting or mixing service applications. A diverting service valve takes common stream and splits it into two outlet force, this configuration is used for applications such as level control and pump bypass control valve.

Mixing service valve combines two fluid streams and discharges the mixed fluid to a common outlet ports this configuration is used for applications where two fluids need to be mixed the end result can range from temperature control to producing a new fluid.

Three way valve actually performs of two opposite acting standard two way valves. So that use of ohe valve instead of two is very economical.

The cast carbon piston valve is manufactured to ANSI class 150 & 300 pressure rating. The PC piston valve is a seatless valve. In PC piston valve, seat and gland are replaced by lower and upper sealing rings. The unique design ensures a long life even at high temperature up to 427 deg C.

This is the simplest form of a ball float trap, with the float attached to the end of a rod. The opposite end of the rod is attached to a discharge valve.
When condensate fills the body of the trap, the float rises which gradually open the discharge valve. Float traps are designed for low & medium Pressure steam heating and process equipment.
