About Pressure Reducing Valve

Pressure reducing valve simply opens by applying spring pressure to a diaphragm. The outlet pressure from it pushes the diaphragm upward at the bottom of the diaphragm, closing the valve. The spring pressure takes over and pushes the valve stem downward, allowing the valve to open when the outlet pressure drops below the valve's set point. The pressure beneath the diaphragm starts to outweigh spring pressure as the outlet pressure rises and approaches the required pressure, driving the valve stem upward and closing the valve. Under specific circumstances, pressure reducing valves can be used to prevent water hammer.

Advanced Corrosion Protection

The valves body is coated with epoxy powder, ensuring exceptional resistance to corrosion in harsh service conditions. This coating prolongs the valves life span, reduces maintenance needs, and contributes to consistent performance when exposed to water, steam, gases, oil, and other aggressive fluids in industrial applications.

Versatile Pressure Management

Designed to regulate pressure with high accuracy, this valve is suitable for a broad pressure range (0.5 to 16 bar) and flow rates up to 50 m/hr. With options for automatic or manual operation and compatibility with a variety of actuators, users benefit from flexible control solutions tailored to specific process demands.

Broad Application and Easy Installation

The valve is engineered for horizontal inline mounting and meets several end standards (ANSI, DIN, JIS), facilitating convenient installation in diverse global systems. Its robust construction and minimized leakage (Class IV/V per IEC 60534-4) make it reliable for water, steam, air, oil, and gas services.

FAQs of Pressure Reducing Valve:

Q: How does the epoxy powder coating enhance the valves performance?

A: The epoxy powder coating provides superior anti-corrosive protection, shielding the valve body from chemical attacks, humidity, and atmospheric exposure, thereby extending its service life and reducing the need for frequent maintenance in challenging environments.

Q: What media can this pressure reducing valve be used with?

A: This valve is compatible with a wide range of media, including water, steam, air, gases, and oil. Its robust construction and high-quality sealing materials make it suitable for regulating pressure in various industrial fluids and applications.

Q: When should a pilot operated versus direct acting pressure reducing valve be used?

A: Pilot operated valves are ideal for processes requiring higher pressure accuracy and large flow rates, while direct acting valves are preferred for simpler installations or systems with lower flow and pressure demands. The choice depends on application requirements and system complexity.

Q: Where is the optimal installation position for this valve?

A: The valve is preferably installed horizontally in an inline configuration. Horizontal mounting facilitates consistent flow control, easier maintenance, and aligns with international standards for industrial systems.

Q: What process is followed to select the appropriate valve model?

A: Selection involves specifying operational parameters such as pressure rating, flow range, temperature, media type, end standards, connection type, installation position, and actuator requirements. These factors ensure the chosen valve matches system needs and performance goals.

Q: How can users benefit from the advanced leakage class of this valve?

A: With a leakage class of IV/V per IEC 60534-4, the valve minimizes fluid loss, enhances process safety, and supports demanding precision and reliability standards in industrial settings, thereby improving overall efficiency.

Q: What are the advantages of using stainless steel for the spring and disc components?

A: Stainless steel springs and discs offer excellent resistance to corrosion and wear, maintaining consistent valve performance under variable fluid conditions and extending operational longevity.
