61LF-PR Series Ball Cone Check Valves

Apollo 61LF-PR Series ball-type check valves have a low-lead bronze body with press connections and are used to provide protection against backflow. Apollo ball cone valves are made of ASTM-approved components, including a corrosion-resistant RPTFE ball and a PTFE seat with an NSF-grade EPDM seal. These can be mounted vertically and horizontally and can work at temperatures up to 250 degrees Fahrenheit with 250 psi of maximum water pressure.

Features

  • Apollo check valves come in bronze and stainless steel variants, offering exceptional corrosion resistance.
  • The brand's 61LF-100 Series in-line check valves are suitable against reverse flow, chemicals and corrosion. These Apollo ball valves are installed in either horizontal or vertical orientation with upward flow.
  • Apollo 910WB-LF Series check valves provide spring-aided closing for rapid response control. They are equipped with a Buna-N seat to prevent leakage.
  • The brand's 163T-LF Series swing checks feature a Y-pattern allowing easy horizontal and vertical lines with upward flow for seamless integration into different system configurations. They include a PTFE seat to add a layer of protection against reactive and corrosive chemicals.

Working Mechanism

  • When the fluid flows in the desired direction, the poppet is pushed open by the flow, allowing the fluid to pass through until the pressure drops.
  • When the flow stops or reverses, the poppet closes, preventing the backflow of fluid into the valve.
  • This poppet is spring-loaded, keeping the valve closed until the fluid pressure is high enough to overcome the spring force and open the valve.

Frequently Asked Questions

How to maintain Apollo check valves?

  • Inspect the working of check valves through the clear cover.
  • Disassemble the valves if necessary and look for damage to the O-ring and valve body.
  • Reassemble the valves after thoroughly lubricating the O-ring with silicone lubricant.

How to install Apollo ball valves?

Insert the Apollo ball valve's input and output into your threaded assembly and screw them. Before installing the handle, ensure it's installed properly (parallel is open).

Are these valves suitable for throttling applications?

While Apollo check valves can be used for throttling, they are not as precise as other valve types. So, if you want a valve only for throttling purposes, then you should go for Apollo globe valves.

Do these check valves require maintenance?

Apollo check valves usually require minimal maintenance. However, inspect them periodically for signs of wear or damage.
