The Protego internal safety valve type SI/F is a shut-off valve and protects the downstream liquid lines of storage tanks and tanks in process plants of the chemical, petrochemical and pharmaceutical industries, thus increasing both safety and availability of the plants.
The internal safety valve SI/F consists of housing, mounting flange, valve seat, valve disc and sealing.
The mounting flange is welded into the tank shell. The valve seat is replaceable.
The valve seat and valve disc are lapped metallic surfaces and an additional O-ring is installed to ensure the required tightness.
The spindle sealing can be adjusted or replaced and is designed for a test pressure of psi: 363 (kPa: 2,500, bar: 25)
