Types of control valve bodies .

The most common and versatile types of control valves are sliding-stem globe and angle valves. Their popularity derives from rugged construction and the many options available that make them suitable for a variety of process applications, including severe service. Control valve bodies may be categorized as below:

• Angle Valves
  • Cage-style valve bodies
  • DiskStack style valve bodies
• Angle seat piston valves
  
• Globe valves
  
  • Single-port valve bodies
  • Balanced-plug cage-style valve bodies
  • High capacity, cage-guided valve bodies
  • Port-guided single-port valve bodies
  • Double-ported valve bodies
  • Three-way valve bodies
• Diaphragm Valves
  
• Rotary valves
  • Butterfly valve bodies
  • V-notch ball control valve bodies
  • Eccentric-disk control valve bodies
  • Eccentric-plug control valve bodies
• Sliding cylinder valves
  • Directional control valve
    
  • Spool valve
  • Piston valve
    
• Air-operated valves
  • Air-operated valve
    
  • Relay valve
    
  • Air-operated pinch valve

Combination Pump combines the titanium sublimation pump with the triode ion pump to economically increase pumping speed while maintaining the feature of ion pump which can easily obtain clean ultra high vacuum.

Features:

1. Increased pumping speed

Compared to ion pump, the cost (including cost of control equipment) per pumping speed 1L/s is approximately 1/2 to 1/3.

2. Light weight and compact

Compared to ion pump with the same pumping speed, the volume and weight are reduced to 1/5 to 1/10. Therefore, it can be easily attached/removed to/from the pumped system to achieve high pumping speed with minimum space.

3. The pump is a collection of pumping, separation and transmission with advantage of high flow, reasonable and compact design, low noise, long working life, aluminum die casting, beautiful modeling.

Applications:

1.CP1,CP3 combination pumps for fuel dispenser can also be used to transfer other gas.

2.CP2 gear pump with cast iron body is applicable to gasoline, kerosene, diesel and gasohol.

3.CP4 combination pump is a vane pump with high flow rate which can reach up to 140L/min. This pump for fuel dispenser can also be used to transfer other gas-liquid mixture with the function of separation the air from gasoline, kerosene, diesel, etc.

4.CP5 Gear Pump, whose material of bady is alloy aluminum founded under low pressure, is applicable to gasoline, kerosene , diesel oil and compound of them, Air separator, by pass valve, check valve, inlet and outlet strainer, relief valve are built in.
