HT7300 Globe High Pressure Control Valve For Nuclear Pump Detection Test
Angle-type high-pressure valves can only be used in angle-type installations. If there is no such pipeline on site and the pressure is quite high, it becomes inevitable to choose a straight-through high-pressure valve. The straight-through high-pressure valve has the characteristics of straight-through installation. The valve body is forged and has good pressure resistance and temperature resistance. If there is a high pressure differential valve.
● The overall design concept of standardization, fewer parts and easy maintenance is implemented throughout;
●Small size, light weight, large output force, fast response, good rigidity and beautiful appearance;
● Simple structure, simple action principle and simple pipeline;
● Four specifications of actuators are designed to meet applications with different pressure differences, reducing the need for spare parts;
● The constant voltage can be freely set to change the output force based on the actual situation on site;
● It is very convenient and convenient to replace the air opening and air closing by changing the pipeline.
● Easy to implement, there is no need to remove the diaphragm cover to replace the air opening and air closing like traditional actuators.
Determined according to our company's regular configuration and customer requirements. If there are no special requirements, our company's regular PSL domestic actuators will be used.
Parameters and Performance
Valve type: straight-through high-pressure structure
Nominal diameter: DN20~DN200
Pressure level: ANSI CLASS 900,1500,2500;
Or JB/T79-94 PN10MPa; PN22MPa; PN32MPa flow characteristics: straight line, equal percentage
Flow coefficient: see Table 1
Adjustable ratio: 30:1
Allowable pressure difference: The allowable pressure difference of the valve is greater than the actual working pressure difference. The manufacturer determines the size of the actuator based on the actual working pressure difference.

For electric, electronic and intelligent types, please see the separately purchased actuator.
Filling: Reinforced PTFE V-shaped packing; PTFE asbestos; flexible graphite
Flange type (FM, RJ type)
ANSI CLASS 900,1500,1500 according to ANSIB16.5-1981 standard
regulations or according to JB/T79-94, HG20592-97 standards butt welding connection (BW)
Surface coating color: The appearance combines aesthetic principles and special surface treatment, and the appearance is very delicate and beautiful. The carbon steel valve body is uniform dark gray, the stainless steel valve body is natural color, the bracket connector is stainless steel natural color or dark gray, the actuator is yellow, and the handwheel seat is gray.
Identification of components: The main components such as valve body, valve core, valve seat, etc. are marked with materials, numbers and identification numbers. First, it facilitates factory management.
The second is to fully consider the customer's perspective when ordering spare parts.
Special requirements: material inspection, liquid penetrant testing (PT), radioactive testing (RT), flow characteristics inspection, steam inspection, complete oil ban, water removal treatment.
