RVHX dark rod type hand wheel gate valve

  • Information
  • 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/closing state of the pipeline water source and ensure the water supply 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
