The Glass pressure relief valve is a simple valve used for controlling and limiting the level of pressure levied on the system or the vessel that can be built by a process, equipment or instrument failure, or the fire. In a Pressure Relief Valve, the pressurized gas is flown into the system to release the pressure.
The glass pressure relief valve is outlined in such a way that it releases a prearranged set of pressure to keep the Glass vessels safe and also prevents other equipment from being harmed due to the intense pressure released exceeding the limit of their design. When the pressure exceeds its limits, the glass pressure relief valve opens up forcefully and releases a small portion of the gas or fluid that helps in maintaining the appropriate pressure in the system.
The Safety Pressure Relief Valve is designed and made up of borosilicate glass and PTFE. The maximum suggested operating temperature of the system is 150°C as well as it works fine under a wide range of pressure.
Working & Operation
A simple connection is offered for the safety of the vent as well as after each operation; the valve tends to reset itself without any labor or the material cost of a split disk replacement.
This freshly developed concept of glass pressure relief valve seat production caters to a pressure seal for the seat. The pressure on the seal will increase with the building up of the inlet pressure. The lip present can achieve this on the inner diameter of the seat that is pressing on the side of the plunger.
The pressure of the seat never gets balanced with the weight load as it has in the traditional pressure relief valves as it is not dependent on the weight load for the pressure of the seal. The physical contact between the PTFE seat and the low Friction PTFE plunger allows an easy plunger eviction from the seat at the initial pre-set pressure. Due to a sharp increase in the seat pressure, the valve gets sealed and restricts the gases as well as liquids.
The Glass Pressure Relief Valve is admirably suited to control different levels of pressure inside all types of reactors as well as the vessels where a relief valve Is needed to seal the system against both the gases as well as the liquids.
It can withstand a maximum temperature of 300°F and can take a thermal shock up to 200°F.
Benefits of Glass pressure relief valves
The Ablaze Export PTFE pressure relief valves were manufactured to use on the systems that require the corrosion resistance ability possessed by PTFE. The operating principle remains constant as priorly used in the regular line of the Safety Pressure Relief Valves having corrosion resistance qualities made from the borosilicate glass.
Ablaze Export glass pressure relief valves have the corrosion-resistant qualities against all liquids as well as gases other than the hydrofluoric acid and the hot concentrated caustics. The Ablaze Export Pvt. Ltd. assures a perfect seal against all our manufactured equipment, as well as liquids and gases.
