ตัวแทนจำหน่าย Fisher by Emerson H120 Series Relief Valves ในประเทศไทย
The Fisher Type H120 is a compact, direct-operated relief valve that utilizes a spring-opposed poppet assembly featuring a Nitrile (NBR) disk. When inlet pressure exceeds the spring setting, the poppet and disk assembly lift off the metal seat to relieve excess pressure.
This valve is available with a selection of springs to support fixed relief pressure settings from 35 to 350 psig (2.4 to 24.1 bar), making it ideal for applications where venting to atmosphere is acceptable and the process media is compatible with Nitrile.
Its straightforward design and wide range of pressure settings make the Type H120 suitable for use in:
• Pneumatic control lines for air tools (e.g., jackhammers and air drills)
• High-pressure installations such as side outlets of Type 1301F regulators
Features
Compact Design
• Small form factor allows installation in space-constrained environments.
Cost-Effective Solution
• Offers a low initial investment, easy installation, and excellent flow capacity per cost, providing economical overpressure protection.
Robust and Corrosion-Resistant
• Constructed from brass or stainless steel with a stainless steel spring, offering enhanced durability and resistance to environmental corrosion. The preset, pinned spring retainer prevents unauthorized adjustment of the relief setpoint.
Optional Protective Cap
• The Type P206 raincap can be added to the outlet to prevent the ingress of debris, trash, or environmental contaminants.
Installation Guidelines
• The Type H120 relief valve can be installed in any orientation, provided that the discharge does not pose a fire, toxic, or explosion hazard. It is critical to ensure the outlet remains unobstructed and free from materials that could affect venting performance.
To maintain reliable operation:
• Use a Type P206 raincap for outlet protection.
• Inspect the valve and installation for compliance with local and national codes.
