Return transmitter ball valve - return transmitter manual ball valve
Model: HQ411F-16P
Alternative name: signal ball valve with travel switch ball valve with valve position display ball valve with limit switch
Brief introduction of the ball valve with the transmitter:
The manual ball valve of the transmitter provides the valve position switch display function for the remote control of rotary valves and actuators. It can be adjusted according to different viewing angles and directions, and the angle of the indicator can be fine tuned to facilitate real-time observation of the correct position of the valve from any position on the top and side.
Installation and use of answering machine:
1. Move the valve to the off position and adjust the red cam so that the "off" switch has a signal output.
2. Move the valve to the open position and adjust the red cam so that the "open" switch has a signal output.
3. Move the valve back and forth several times to ensure that the limit switch signal is reliable.
Echo product features
1. The three-dimensional position indicator can clearly show the position of the valve.
2. Die cast aluminum alloy shell, powder coating, compact design, beautiful appearance, reduce the valve packaging volume, and reliable quality.
3. Double line interface, double 1/2 NPT pipe interface.
4. Signal feedback device.
5. The switch position can be clearly identified by the indicator.
6. The multi contact internal circuit board is connected with 8 contacts (6 for switches, 2 for solenoid conduit connection). The wiring board meets the standard of microswitch, with DPDT switch and valve position transmitter (4~20mA), mechanical microswitch, proximity switch, magnetic switch, etc., and can be used for the connection of solenoid valve.
7. "Quick position" cam; The adjustable cam of the limit switch is installed through splines and springs; The position of the switch cam can be quickly adjusted without tools.
8. Replace wiring with PCB board to prevent short circuit.
9. Ambient temperature: - 20~70 ℃, waterproof and dustproof protection grade: IP67, explosion-proof grade: ExdII BT6, Eexd IICT6, in accordance with EN50014/50018 standard.

11. The bracket is easy to install. There are four types of brackets that comply with NAMUR standards, and the bracket complies with ISO5211 standards. Any rotating actuator can be easily installed.
12. Anti falling bolt, the bolt attached to the upper cover will not fall off during disassembly.
13. It is easy to install, and the stainless steel main shaft connection part and mounting bracket comply with VDI/VDE 3845 and NAMUR standards.
14. Anti corrosion.
15. There are standard type and explosion-proof type.
The return valve is a kind of field instrument used to detect the valve status in the automatic control system, which is used to output the opening or closing position of the valve as a on-off signal, so that the control room can confirm the opening and closing status of the valve. It can be remotely and centrally controlled to meet the needs of computer program control. It is widely used in petrochemical industry, gas equipment, electric power equipment, environmental water treatment, HVAC, iron and steel metallurgy, industrial kilns, canned equipment, brewing equipment, drying equipment, vacuum equipment, surface treatment, biopharmaceuticals, food machinery, textile printing and dyeing, paper making and other industries.
