Preferred SS316 Direct Acting Pressure Relief Valve for Food, Pharmaceutical, and Industrial

Model RLT/RLF is a direct-acting relief valve, also known as a direct-acting pressure relief valve(PLV). It is a type of safety valve used to control or limit pressure within a system. Without such protection, pressure can build up, potentially causing process disruptions, equipment or instrument failures, or even fire hazards.

Key Features and Benefits of Direct Acting Pressure Relief Valve

• The pressure relief valve acts as a safety device to release excess pressure, preventing damage within the system.
• The direct-acting pressure relief valve is suitable for general liquids and gases.
• Ideal for process automation control and various general-purpose applications.
• Designed for convenient installation with in-style mounts that support both horizontal and vertical orientations.
• Offers a wide capacity range to handle local water supply pressure and accommodate specific pump requirements.
• Features an adjusting nut that allows easy and precise pressure calibration.
• Constructed with durable SS316 stainless steel lower and upper bodies for enhanced compatibility and longevity.
• Easy to maintain, with maintenance kits available upon request.

How to adjust a Direct-Acting Pressure Relief Valve: Step-by-Step Guide

Step 1: Loosen the lock nut on the adjusting stem. Then, turn the adjusting screw counterclockwise to reduce the outlet pressure to its lowest setting.

Step 2: Slowly turn the adjusting stem clockwise while monitoring the pressure gauge until the desired upstream pressure (set-point) is reached. Make sure to adjust gradually and verify system stability after each change.

Constructed from corrosion-resistant, high-strength 316 stainless steel, these units deliver precise overpressure relief and effective water hammer mitigation, ensuring stable and continuous plant operation under demanding industrial conditions.

Frequently Asked Questions (FAQ) about Direct Acting Pressure Relief Valve

Q1: What is a pressure relief valve?

A pressure relief valve is a safety device designed to protect pipelines, pumps, and equipment from excessive pressure. It automatically opens to release surplus pressure and closes once the system returns to safe levels.

Q2: How does a pressure reducing valve differ from a pressure relief valve?

A pressure reducing valve maintains a consistent outlet pressure for stable system operation, while a pressure relief valve protects the system by discharging excess pressure when the inlet pressure exceeds safe limits.

Q3: Why choose a stainless steel (SS316) pressure relief valve?

SS316 provides excellent corrosion resistance, durability, and hygienic safety, making it the ideal choice for potable water, food & beverage, pharmaceutical, and demanding industrial applications.
