Resilient Seat Gate Valve vs. Triple Offset Disc Butterfly Valve: What’s the Difference?

Resilient Seat Gate Valve vs. Triple Offset Disc Butterfly Valve: What’s the Difference?

Aug 27, 2024 | News

When selecting industrial valves, it’s crucial to understand the differences between a Resilient Seat Gate Valve and a Triple Offset Disc Butterfly Valve. These valves serve distinct purposes and are designed with specific features that make them ideal for various industrial applications. As a manufacturer offering OEM & ODM services, wholesale options, and customization, we cater to the unique needs of our clients. This article explores the key differences and benefits of each valve, helping you make an informed decision.

Resilient Seat Gate Valve

Understanding Resilient Seat Gate Valves

A Resilient Seat Gate Valve is a type of valve commonly used in water, oil, and gas pipelines. Its primary function is to completely shut off the flow or allow full flow through the valve with minimal resistance. The resilient seat ensures a tight seal, reducing the risk of leaks even under low pressure.

Key features of a Resilient Seat Gate Valve include:

  • Durability: Designed for long service life, often up to 50 years.
  • Tight Seal: The resilient seat provides a flexible yet secure closure.
  • Low Maintenance: Simple design with fewer moving parts reduces the need for frequent maintenance.

These valves are ideal for applications where tight sealing is essential, such as in water supply systems, oil pipelines, and other fluid-handling systems.

What is a Triple Offset Disc Butterfly Valve?

The Triple Offset Disc Butterfly Valve, often referred to as a triple eccentric metal seal butterfly valve, is a highly specialized valve used in high-pressure and high-temperature environments. The triple offset design means the disc and seat are never in direct contact except at the final point of closure, reducing wear and ensuring a tight seal.

Key benefits of a Triple Offset Disc Butterfly Valve include:

  • High Performance: Suitable for demanding applications with extreme pressure and temperature.
  • Extended Lifespan: The metal-to-metal seal enhances durability.
  • Reduced Wear: The triple offset design minimizes friction and wear, leading to lower maintenance costs.

This type of valve is commonly used in power plants, chemical processing, and other industrial environments where reliable operation under harsh conditions is critical.

Comparing the Two: Which One is Right for You?

When deciding between a Resilient Seat Gate Valve and a Triple Offset Disc Butterfly Valve, consider the specific requirements of your application. If you need a valve for low-pressure systems with a focus on preventing leaks, the Resilient Seat Gate Valve is an excellent choice. However, if your application involves high pressure, high temperature, or both, the Triple Offset Disc Butterfly Valve offers superior performance and longevity.

Triple Function Air Vents: An Essential Accessory

In addition to these valves, triple function air vents are critical for maintaining pipeline integrity. They help release air from the system, preventing pressure build-up and ensuring smooth operation. Whether you’re using a Resilient Seat Gate Valve or a Triple Offset Disc Butterfly Valve, installing triple function air vents can enhance system efficiency and safety.

Resilient Seat Gate Valves With Non-Rising Stem Feature For Underground Applications

Resilient Seat Gate Valves With Non-Rising Stem Feature For Underground Applications

Feb 21, 2024 | News

For underground water distribution systems, gate valves with non-rising stems are commonly used to isolate sections of piping for repairs or maintenance. One type that excels in buried applications where debris is a concern are resilient seat gate valve featuring this non-rising stem design. Certainly, aiming to the applications of underground, we also call this kinds of valves as underground gate valve or underground gate valve. Let’s explore why these valves are well-suited for underground pressure piping.

What is A Resilient Seat Gate Valve?

Gate valves contain a wedge-shaped gate that slides vertically to open or close flow. Period, resiliently seated gate valves improved upon traditional designs by using an elastomeric seal bonded to the gate rather than a mechanical seal.

This not only provides drip-proof shutoff, but also allows the valve to be used in either flow direction. Furthermore, elastomeric seals are less susceptible to damage from sand or grit than metal-to-metal sealing surfaces.

Non Rising Stems Prevent Damage

Whether the valve is open or closed, the concealed stem remains in the same vertical position relative to the valve body. This protects the operating nut and valve stem from damage during installation or if debris gets under the valve.

With a rising stem valve, the stem rises when it opens. Plus it goes down when closed. If subsurface conditions change over time, valve stems are at risk.

However the non-rising stems are only slightly above the ground to avoid snag hazards. This is why we suggest about China non-rising stem gate valve.

Top Benefits For Buried Piping Applications

  • Drip-tight sealing withstands system pressure surges and prevents leaks even in gritty or sandy soil conditions.
  • Corrosion-resistant ductile or bronze bodies hold up well underground for decades of use.
  • Buried valves eliminate risk of unauthorized access or tampering with surface-mounted valves.
  • Non-rising stems protect the stem and operating mechanism from debris entering the valve body.
  • Extended operation in either flow direction using tapped or flanged end connections.
  • Test and operate valves with standard pentagonal wrenches without needing to excavate.

Suitable For Pressures To 250 PSI

Most resiliently seated gate valves suitable for underground piping applications are rated for a closing pressure of 150 to 250 PSI (pounds per square inch).

The ductile iron or cast iron gate valve in industrial gate valves can support these pressures in water mains up to 12 or 16 inches in diameter. It will depend on the model.

Flange ends simplify installation using bolted accessories. With proper installation techniques and adequate thrust, gate valves can provide very reliable closure for pipeline repairs near critical facilities.

Ease of Installation And Maintenance

A typical installation of a resiliently seated gate valve requires the lower half of the valve body to be embedded in the ground so that only the operating nut protrudes above the ground.

The surrounding compacted backfill provides support and prevents the valve from moving.

This setup allows access to the valve without digging a small hole around the stem nut. Regular valve exercises and pressure tests verify proper operation for decades of underground use. For maintenance, a simple replacement of the rubber elastic seat is usually sufficient.
