Supplier LESER API 526 Safety Valve, Jakarta
WWW.DISTRIBUORALATINDUSTRI.COM | Supplier LESER API 526 Safety Valve, Jakarta | LESER API 526 Safety Valve is a high-performance spring-loaded safety valve / pressure relief valve (PSV/PRV) designed for reliable overpressure protection of pressure vessels, piping systems, process equipment, boilers, heat exchangers, and other pressurized industrial systems. The valve is designed in accordance with the dimensional and application requirements associated with API 526, which is widely used for standardized flanged steel pressure relief valves in the petroleum, petrochemical, chemical, and process industries. The safety valve operates using a direct spring-loaded mechanism, in which the process pressure acts on the valve disc while a calibrated spring provides the closing force. During normal operation, the spring keeps the disc securely seated; when the system pressure reaches the specified set pressure, the disc lifts and the valve releases excess steam, gas, vapor, or liquid to prevent the protected equipment from exceeding its allowable pressure. After the pressure decreases to the appropriate reseating pressure, the valve closes again and restores the system to normal operation.

API 526 provides standardized dimensions and requirements for flanged steel pressure-relief valves, particularly for refinery, petrochemical, and process applications. Standardization of the inlet/outlet dimensions and orifice designations makes it easier to select and replace pressure relief valves while maintaining compatibility with the existing piping and equipment arrangement.
The API 526 specification is particularly important when specifying:
- Valve inlet size
- Valve outlet size
- Pressure class
- Orifice designation
- Flange dimensions
- Pressure relief capacity
- Installation compatibility
Operating Principle
The LESER safety valve works automatically according to the following sequence:
Normal Operation → Valve Closed → Pressure Increases → Set Pressure Reached → Disc Lifts → Valve Opens → Excess Pressure Released → Pressure Decreases → Valve Reseats
For correct sizing and specification, the following information should be provided:
- Valve type/model
- Inlet size
- Outlet size
- API 526 orifice
- Pressure class
- Set pressure
- Operating pressure
- Relieving pressure
- Process temperature
- Relieving temperature
- Process medium
- Required relieving capacity
- Backpressure
- Body material
- Seat material
- Bonnet configuration
- Bellows requirement
- Certification requirement
