Product Description

Overview of Ax46F pilot operated safety valve

Pilot operated safety valve model: AX46F	Pilot-operated safety valve nominal diameter: 25MM-200MM	Pressure of pilot operated safety valve: 1.6MPA 10.0MPA
Connection mode of pilot operated safety valve: flange connection	Pilot type safety valve form: pilot type	The main function of pilot-operated safety valve: pressure relief protection
Pilot type safety valve using medium: natural gas, gas	Pilot type safety valve material: cast steel. Stainless steel	Pilot operated safety valve standard: mechanical ministry standard or custom non-standard

Pilot-operated safety relief valve is a safety valve with novel structure. It is mainly used in oil and gas, chemical industry, electric power, metallurgy and city gas, etc. It is the best overpressure protection device for pressure equipment, container or pipeline. Its main advantage is that the direct effect of the change spring is the indirect effect of the pilot valve, which improves the sensitivity of the action, and the main valve adopts the sleeve piston type, double sealing valve seat structure, high precision of action, good repeatability, fast return to the seat, no leakage, high back pressure discharge, long working life, stable and reliable, it can also be adjusted online, after repeated jump discharge, it can still automatically return to the seat. Close tight, easy to operate and maintain

Main items of safety valve order:

Safety valve medium, pressure level, opening mode (full opening/micro opening) set the take-off pressure, determine the valve size, connection mode, standard maximum temperature resistance, release flow/hour, valve body material, internal valve body structure, working principle, installation instructions and other related technical data. Safety valve selection is mainly based on (take-off pressure and neat pressure flow temperature) caliber general design institute will be given, and in fact through the steam pressure, flow and take-off pressure, you can infer the size of the safety valve. Generally, it will be smaller than the caliber selected by the design institute. When the occasion is very important or the environment is more complex, please try your best to provide design drawings and detailed parameters, by our Xuan Cheng valve company experts for your review.
