The RELT-SLP / RELF-SLP Micro Pressure Type Pressure Reducing Valve(PRV), also known as Ultra-low Pressure Regulator, is specially designed for applications requiring outlet pressures below 1 kgf/cm². Its large diaphragm provides a highly sensitive mechanism for precise pressure adjustment, making it ideal for air and gas systems.

Difference between RELT / RELF vs RELT-SLP / RELF-SLP models

Both RELT/RELF and RELT-SLP / RELF-SLP are direct acting pressure reducing valves. The RELT / RELF series is designed for low-pressure applications with a pressure range of 0.2–1.5 bar, while the RELT-SLP / RELF-SLP series targets ultra-low pressures with ranges of 0.03–0.15 kgf/cm² and 0.08–0.4 kgf/cm², providing highly sensitive and precise control for air and gas systems.

Key Features and Benefits of Micro Pressure Type Direct Acting Pressure Reducing Valve

• Micro Pressure Type Direct Acting Pressure Reducing Valve is ideal for general gas systems, ensuring stable pressure control.
• Large diaphragm design provides high sensitivity for precise and responsive pressure regulation.
• Suitable for process automation and a wide range of industrial, electronics, and semiconductor applications.
• Adjusting the nut allows easy and accurate pressure calibration.
• SS316 lower and upper bodies offer excellent corrosion resistance and long-term durability.
• Balanced piston design maintains consistent outlet pressure even when inlet pressure fluctuates; supplied pressure gauge displays the outlet pressure.
• Easy to maintain, with maintenance kits available upon request.

Frequently Asked Questions(FAQ) about Micro Pressure Type Direct Acting Pressure Reducing Valve

Q: What are typical applications for ultra-low pressure reducing valves?

They are commonly used in precise water distribution, irrigation systems, laboratory setups, or equipment requiring minimal outlet pressure.

Q: How should the Micro Pressure Type Pressure Reducing Valve be adjusted?

Mount the pressure reducing valve horizontally with the shutoff valve closed. Set the adjusting stem fully counterclockwise to the minimum pressure. Gradually open the shutoff valve while monitoring the pressure gauge to ensure readings remain within safe limits. Then, turn the stem clockwise to achieve the target set pressure and secure the adjusting nut.
