APOLLO VALVES 16-501-02 Adjustable Relief Valve, Cast Bronze, MNPT, FNPT, 1/2 Inch Inlet, 1/2 Inch Outlet

Apollo 16-501-02 adjustable relief valve is ideal for safeguarding systems by releasing excess pressure, preventing potential rupture or explosion. This valve is used in the manufacturing, petrochemical, oil & gas and pharmaceutical industries. Its adjustable nature allows precise pressure setting, ensuring controlled operation.

Working Mechanism:

• When pressure within a system increases due to fluid expansion or other factors, the relief valve senses this buildup.
• The rising pressure exerts force on the nitrile disc situated within the valve.
• As the exerted force exceeds the seating force, the nitrile disc lifts off its seat, creating an open pathway.
• With the disc lifted, pressurised fluid flows through the open path, directed towards the valve's outlet.
• As fluid exits, the pressure within the system begins to decrease, allowing pressure to balance.

Features:

• This valve features bronze construction for enhanced durability & corrosion resistance.
• It has an MNPT inlet and an FNPT outlet for seamless integration into various setups.
• This valve has a disc composed of nitrile material, which enhances its sealing capabilities.
• It further features a nitrile seal for excellent chemical resistance & reliable sealing performance.
• This valve can operate at temperatures ranging from 0 to 200 degrees F.
• It has a spring inside valve made of stainless steel, ensuring durability and resistance to corrosion.

Frequently Asked Questions:

Q. How does the adjustable feature of this relief valve work?
