🔧 WORKING PRINCIPLE OF SAMYANG PRESSURE REDUCING VALVE

(Samyang Korea – Pressure Control Valve Function & Applications)

1️⃣ Introduction to Samyang Pressure Reducing Valve

Samyang pressure reducing valve is an automatic pressure control device widely used in steam, air, water, and hydraulic systems.
Manufactured in Korea, Samyang valves are designed to stabilize outlet pressure, protect equipment, and extend the lifespan of piping systems.

2️⃣ Working Principle of Samyang Pressure Reducing Valve

In the initial position, the valve is fully open, and the outlet opening is adjusted by a set screw.
When the outlet pressure increases above the set value:

• The control piston is pushed upward, reducing the outlet area, which lowers the outlet pressure.

• Conversely, when the outlet pressure decreases, the piston moves downward, increasing the outlet area, stabilizing the pressure again.

This continuous self-balancing process keeps the outlet pressure constant despite fluctuations in the inlet pressure.

⚙️ Key Features:

• Maintains accurate, stable, and safe pressure control.

• Adjustable closing speed eliminates pressure fluctuations.

• Reliable operation and flexible installation without affecting performance.

3️⃣ Applications of Samyang Pressure Reducing Valve

Samyang pressure reducing valves are applied in a wide range of industries:

• 🏭 Hydraulic systems in industrial machinery

• 🌊 Water supply and treatment systems

• ⚙️ Compressed air and pneumatic pipelines

• 🍲 Food processing equipment and pressure cookers

• 🔥 Steam and boiler systems

4️⃣ Working Principle of Samyang Pneumatic Pressure Reducing Valve

The Samyang pneumatic pressure reducing valve operates based on pressure differential between the diaphragm and piston.
When the inlet pressure increases:

• The spring acts in the same direction as the inlet air, pushing the piston downward → valve closes → reduces outlet pressure.

• When the outlet pressure drops, the valve opens again, maintaining steady output pressure.

Applications:

• Commonly installed before butterfly valves, ball valves, or gate valves to control pressure.

• Helps protect downstream equipment and pipelines, ensuring system stability and safety.

5️⃣ Working Principle of Samyang Water Pressure Reducing Valve

The Samyang water pressure reducing valve is designed to reduce and stabilize water pressure in residential, industrial, and fire-fighting systems.

Adjustment Instructions:

• To decrease outlet pressure: turn the adjustment screw counterclockwise.

• To increase outlet pressure: turn the screw clockwise.

Applications:

• 🏢 High-rise buildings and apartments

• 🚰 Clean water supply systems

• 🔥 Firefighting pipelines

• 🧼 Domestic water, filtration systems, and heaters

Without a water pressure reducing valve, excessive pressure may damage pipes, filters, and sanitary equipment, or cause leaks throughout the system.

6️⃣ Working Principle of Samyang Steam Pressure Reducing Valve

Samyang steam pressure reducing valve is a mechanical device that stabilizes steam outlet pressure in boiler and production systems.

Main Components:

• Valve body

• Diaphragm or piston

• Spring adjustment assembly

• Lock nut and cover cap

How It Works:

• When the spring is compressed, it applies force to open the valve → increasing steam flow.

• As outlet pressure rises, the feedback force from the diaphragm or piston pushes against the spring, partially closing the valve and maintaining stability.

• Operates automatically and precisely with pilot control system, preventing sudden pressure surges downstream.

Advantages:

• Maintains constant outlet pressure for heating, drying, and steaming processes.

• Fast response time and high accuracy.

• Protects downstream valves and equipment from overpressure damage.
