Overview:
In the fire water supply system and automatic sprinkler system, the fire-fighting gate valve is usually used as a monitoring valve for the water supply pipeline to monitor the opening/cutting status of the pipeline water source and ensure the safety of the fire protection system.
Features:
Fire-fighting design
Based on the elastic seat sealing gate valve, the company specializes in the development and production of fire protection systems. valve
Door strength, sealing performance, operating performance, circulation capacity and other indicators have passed
Strict FM certification inspection.
◆ Strong and durable structure
The body is cast in high-strength ductile iron and can withstand high pressure (4 times nominal pressure).
Resist the impact of heavy objects in harsh environments. Meet the overpressure of the fire system to the strength of the valve
All requirements.
◆ Zero leakage and low torque
The rubber-elastic spool is perfectly fitted to the flat-bottomed seat, ensuring zero leakage when the valve is closed.
Only a low torque is required when opening. Ensure that the fire protection system can be easily used by an individual in an emergency
Operate the valve.
◆ Full flow "zero" loss
The valve core can be completely hidden in the cavity, the bottom of the valve body is straight through without grooves, and the same full basin
Straight through the pipe, it is not easy to accumulate debris. Valve head loss is close to zero, meeting the elimination system tight
The maximum flow requirement in an emergency.
◆ Anti-corrosion and long life
The inner and outer surfaces of the valve are painted with epoxy resin to meet indoor, outdoor, underground, etc.
Long life requirements for fire protection piping in harsh environments. The overall rubberized valve core, stainless steel valve stem. green
Copper bearing, to ensure that the pipeline will not be used for a long time, the valve will not be affected by rust.
Fire fighting.
◆ On-site remote monitoring
Depending on the position of the valve stem or stroke pointer, the valve opening condition can be monitored on site. When the valve
When the door is mistakenly closed, an electrical signal can also be transmitted to the control center to monitor the water supply pipeline in real time.
The opening condition of the valve ensures the safety of the water supply of the fire protection system at all times.
◆ Online replacement maintenance
Three "O" shaft seal design, self-sealing bonnet, tight seal, greatly reducing valve leakage
Possible. In the case that the pipeline does not stop water or reduce pressure, the shaft seal seal can be replaced to meet
Fire system continuous water supply requirements
