Регуляторы второй ступени Fisher R622, R642 и R652 для сжиженного газа

Основные преимущества и выгоды

• Superior Relief Performance: Each regulator in the R600 series features a high-performance relief valve and a large 3/4-inch screened vent. This system is designed to limit downstream pressure to less than 2 psig (0.14 bar) even in severe overpressure situations.

• Improved Accuracy: Advanced internal geometry and sensitive diaphragms provide better pressure regulation, ensuring consistent flame heights and efficient appliance operation.

• 20-Year Recommended Replacement Life: Built for longevity, the R600 series is manufactured with high-quality materials to provide two decades of reliable service in outdoor environments.

• Corrosion-Resistant Materials: Constructed with advanced coatings and materials that resist the degrading effects of weather and atmospheric salt, maintaining the integrity of the regulator over its entire lifespan.

• Debris Protection: A standard inlet screen prevents pipe scale and contaminants from reaching the valve seat, reducing the risk of leaks or regulator failure.

• Easy System Diagnostics: Integrated test ports allow technicians to perform pressure checks and system troubleshooting quickly and accurately without breaking piping connections.

• Positive Drainage: The design ensures that moisture and condensation drain away from the critical internal components, preventing freeze-ups in cold climates.
