Pneumatic V-type regulating ball valve is a kind of rotary ball valve with metal core seat or metal …

Description:

A brief introduction:
ZSHV series V type pneumatic ball valve Is a core seat is made of metal or metal, rotating ball valve on the PTFE sealing, it will control the characteristics of ball and butterfly valves are combined into a whole, can be used as a control valve, but also can be used as a cut off valve.
A field of application:
ZSHV series V type pneumatic ball valve The ball core is in V shape, and can realize the linear adjustment, adjustable range. When the valve is closed, the gap between V type and shear wedge seat production, not only has the self-cleaning function and can prevent the ball stuck, especially suitable for freezing pipeline occasions. V type pneumatic ball valve suitable for control of pulp, wastewater containing fibers and particles suspended solid medium and granular medium. Equipped with piston cylinder actuator has the advantages of simple structure, large output torque. This series of ball valve according to the sealing performance is divided into soft seal and seal; by adjusting the way into regulating and cutting type, single and double acting type cut off by the form of points, adjusting for double acting type. The unique advantages of single action is that once the power source failure, valve control system requirements will be automatically in the closed or open position. The products are widely used in electric power, petroleum, chemical, papermaking, textile, food, pharmaceutical, aerospace and other fields.
Three, V type pneumatic ball valve The main features:
1, advanced control valve of a right angle turn structure. V type ball valve repair without a long, long service life, to provide you with the real efficiency of a process control valve condition.
2, excellent regulation characteristics: the inherent flow characteristics of V type valve has a similar percentage and adjustable up to 300:1 ratio. So V type valve can provide precise control in a wide range of rate changes.
3, the maximum flow capacity: because of its streamlined shape and full right angle turn control reasons, the maximum volume is particularly high, particularly through capacity, small flow resistance, so it can use a smaller valve size is more economical and practical.
4, V type valve dual bearing structure, high mechanical stability, starting torque is small, the valve sensor with excellent sensitivity and speed.
5, the maximum reliability (safety): the body as a whole structure, durable, operation will not be affected by pipe pressure, and can avoid the leakage of the valve body.
6, superior sealing metal seat: V type valve with movable metal seat, with the help compensation, and has superior sealing performance and long service life. In the flow, leakage rate of 10 rated flow coefficient.
The shear capacity of 7, super: V type valve adopts a metal seal structure, V type valve core and metal seat in the process of rotation, V notch and the valve seat to generate a strong shear force to cut off the fibers and other impurities, and has self-cleaning function to prevent the valve stuck phenomenon.
8, V type pneumatic ball valve has the advantages of compact structure, compact and lightweight, easy installation, convenient maintenance.
9, the use of pneumatic actuator cylinder piston and crank conversion structure, large output torque, small volume. The actuator adopts fully sealed waterproof design and high protection level. Imported mirror cylinder block cylinder, without oil lubrication, friction coefficient, corrosion resistance, with superior durability and reliability. All transmission bearings with boundary lubricated bearings without oil lubrication, ensure that the shaft do not wear.
Four, V type pneumatic ball valve The implementation of standards:
1, design and manufacture: GB12237-89, API608, API 6D, JPI 7S-48, BS5351, DIN3357.
2 flange size: JB/T74 ~ 90 (JB74 ~ 90), GB9112 ~ 9131, HGJ44 ~ 76, SH3406, ANSI B16.5, JIS B2212, NF E29-211, DIN2543 ~ 2214.
3, the length of the structure: GB12221-89, B16.10, ANSI JIS B2002, NF E29-305, DIN3202.
4, the main test test: JB/T 9092, API 598.
Five, actuator:
Using the new GT series of pneumatic actuators, a double acting and single acting (spring), gear rack drive, safe and reliable; AW series of large diameter valves using pneumatic actuator fork transmission, reasonable structure, large output torque, a double acting and single acting.
1, dual piston gear, large output torque, small volume.
2, use aluminum alloy cylinder material, light weight, beautiful appearance.
3, manual operation mechanism is installed on the top and bottom.
4, rack adjustable opening angle of connection, the rated flow.
5, the execution of instructions and all kinds of accessories for automatic operation of optional electric signal feedback device.
6, the IS05211 standard connection for the installation of the product provides a convenient replacement.
Section 7, both ends of the screw can make the standard product at 0 DEG and 90 DEG with the adjustable range of plus or minus 4 degrees. To ensure the accuracy of the synchronization with the valve.
Attachment options:
According to different control requirements and can choose the following attachments:
Cutting accessories: single solenoid valve, solenoid valve, limit switch back to the hearing.
Regulated accessories: Electrical positioner, pneumatic positioner, electrical converter.
Air handling accessories: air filter relief pressure valve, air frl.
The manual mechanism: HVSD manual operating mechanism
