GAA46H/F Pilot Safety Valve Application:
GAA46H/F pilot safety valve is especially suitable for high back pressure, high flow, high pressure and the application of the installation location and compact spaces. pilot safety valve is mainly used for oil and gas, chemical, electric power, metallurgy, and city gas fields of compression equipment, containers or pipeline over pressure protection device.A46H/F Pilot Safety Valve Work Principle:
When the system work properly, pilot safety valve in the closed state, the system pressure through the inlet pressure tube, and chamber pressure of the valve guide tube tospread to the main valve disc at the top of the dome chamber, which in the main valve produce a net downward force in the valve, main valve is turned off when the systempressure reaches the set pressure, the pilot valve to open and slip the shuttle closed pilot valve inlet channel, the pressure of the main valve chamber through the pilot valve emissions relief, because the system pressure is higher than back seat pressure, sliding shuttle closed the inlet channel, which cut off the flow of fluid in the pilot valve when the pressure of the main valve chamber a sharp decline in the fully open the main valve disc, fluid flow through the main bleed valve buck. when the system pressure falls below a certain value, the pilot valve spring force to overcome the force of the valve inlet pressure acting on the sliding shuttle pilot valve back seat, the top of the peak of the staff open the sliding shuttle, and finally the fluid to re-enter dome of the main valve chamber, close the main valve.
