​Technical specifications

             

Cavitation-Control Type
Power Application     
Features:
 ·Reduce to a lesser extent of cavitation damage on the trim and body 
​ ·Control the speed of the fluid going through the valve and reduce the damage of flash to the valve body. 
 ·Adapt to various flow conditions.
 ·If cavitation occurs when valves start, This valves is in good condition.
 ·Cage guiding effect on double-entry-type stem guide serve as the role of strengthening. 

​Typical Application 
 ·Water-sprayed desuperheating control Valve
 ·Deaerator level control valve
 ·Boiler feed-water regulator (in the occasion of not using pneumatic valve)
 ·Condensate recirculation system
 ·other applications of lesser cavitation  

Power applications       
Cavitation - elimination type
Features:
 ·Pressure drop in stages to eliminate cavitation 
 ·Since the control of the rate of fluid motion and reduction of the fluid collision, the internal components of the valve life has been greatly extended 
 ·Since the flash is controlled, the valve is not damaged during startup 
 ·Flow-shut structure can eliminate the hazards of solid pigment and allows the valve to close more tightly
 ·Each spool is specially designed for specific applications
 ·Easy to remove and to clean

Typical applications
 ·Boiler feed-water recirculation system
 ·Feed-water startup regulator
​ ·Bypass regulator of various pumps 
 ·Other applications of lesser cavitation

Power Applications    
Noise Reduction Type
Features: 
 ·Can reduce gas noise while fully maintaining the adjustable ratio of the valve.
 ·A perforated plate can be disposed behind the valve to further reduce noises
 ·The cost of such noise reducing way is low
 ·Control the rate of gas through the trim·
 ·Condensed structure and the maintenance is easy

Typical Applications
 ·Stean of oxygen reduction device 
 ·Pressure reducing device of main steam to auxiliary steam
 ·Steam relief system
 ·Soot blowing system
 ·Main gas pressure regulator (gas) 
 ·Other application of noisy steam or gas

​Other Products 
1 linear control valve :
Valve plug and stem work as a whole. The valve stem is 3-4 times wider comparing to traditional stem. It eliminates the phenomenon of plug stuck and shedding of traditional valve by using double-top orientation outside the fluid; Snap valve seat can be autocentering without grinding when installing , top-in spool makes the valve disassembly very simple.

Pressure range: from vacuum to 15000Psi (100Mpa), temperature range: from -423 ° F (-253 ℃) to 1500 ° F (815 ℃); Valve Size: 1/2'' (. DN12 5MM); body material: carbon steel, stainless steel and alloy materials required. For severe services of high temperature and pressure difference: FLOWSERVE cavitation control valve get controlled in order to protect the trim and body from damage of cavitation; FLOWSERVE cavitation eliminating control valve can completely eliminate the cavitation noise in high differential pressure . FLOWSERVE noise-reducing control valve can greatly reduced noise of the gas, FLOWSERVE tiger teeth control valve can greatly reduce the noise of the gas, and can eliminate the cavitation of liquids.

Made of aluminum and equipped with four-way manual positioner of FLOWSERVE, which can achieve high positioning accuracy,  the upper and lower piston receive the air source pressure at the same time, gas supply cylinder can withstand pressures up to 10KG per square centimeter. Inside of the cylinder, there is a cut-off relief spring , The spring only decisive role when there is something wrong with the air source. The acting direction of the spring can be interchanged  at the using site . FLOWSERVE cylinder actuator has light weight , small size, high thrust, fast stroke and is durable.

3 Rotary Control Valve :
Appliable to lower large differential pressure and big flow regulation, and can also be used as a control switch.
