Relief Valve Stem – Vulcanized Seat

Description

A relief valve stem – vulcanized seat is a type of relief valve that uses a vulcanized rubber seat to seal against the valve body. Vulcanized rubber is a type of rubber that has been heated and cured under pressure, which gives it its strength and durability.

Relief valves are used to protect systems from overpressure. When the pressure in the system exceeds a certain set point, the relief valve opens and allows the excess pressure to escape. This prevents the system from being damaged.

Vulcanized rubber seats are a good choice for relief valves because they are soft and resilient. This allows them to conform to the valve body and valve disc, creating a tight seal. Vulcanized rubber seats are also resistant to wear and tear, so they can last for many years.

Relief valves with vulcanized rubber seats are typically used in applications where the medium is corrosive or abrasive. They are also used in applications where the pressure is high or where the valve needs to be able to operate reliably for many years.

Here are some of the advantages of using a relief valve stem – vulcanized seat:

• Good sealing performance: Vulcanized rubber is soft and resilient, which allows it to conform to the valve body and valve disc, creating a tight seal.
• Good wear resistance: Vulcanized rubber is resistant to wear and tear, so it can last for many years.
• Good temperature resistance: Vulcanized rubber can maintain its physical and chemical properties over a wide temperature range.
• Good corrosion resistance: Vulcanized rubber is resistant to corrosion by many acids, alkalis, salts, and oils.
