62-100 Series Ball Cone Spring Check Valves

Apollo 62-100 Series ball cone spring check valves ensure that fluids flow in one direction while blocking reverse flow, thereby preventing contamination, system damage and inefficiencies. By allowing the flow of fluids only in the desired direction, these valves maintain the integrity of pipelines, pumps and equipment, enhancing system reliability and safety. They feature stainless steel construction for durability and resisting corrosion on exposed surfaces. These check valves come with threaded FNPT x FNPT connections to simplify installation by securely attaching to pipes or fittings for reliable fluid control. They are equipped with PTFE (Reinforced Teflon) ball checks for corrosion resistance and chemical compatibility. These valves are equipped with stainless steel springs, providing resilience and maintaining long-term valve functionality. They are available in sizes of 1/4, 3/8, 1/2, 3/4, 1, 1.25, 1.5 and 2 inches.

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.
