EPDM Butterfly Valve Liner: Properties, Durability, and Applications

What to Consider When Choose a Keystone Butterfly Valve with EPDM Seat

On this page

EPDM Material Properties

Knowing the characteristics of EPDM (ethylene propylene diene monomer) is essential when choosing a Keystone EPDM butterfly valve liner.  The ability of EPDM to withstand polar substances such water, phosphate esters, ketones, alcohols, and glycols is well known.  It works well with chlorinated water as well, which makes it perfect for uses like swimming pools.  It is not, however, impervious to oils and hydrocarbon solvents.  EPDM can usually function well in temperatures between -30°F and 250°F.  It is a popular option for sectors needing long-lasting sealing solutions because of its strong performance under these circumstances.

 

Assessing Durability and Service Life

Long-Term Performance

The overall lifespan of the valve is largely dependent on the service life of the butterfly valve liners. With an airtight seal, EPDM liners can withstand more than 10,000 cycles. This is especially helpful in settings where the valve is opened and closed a lot. The valve's appeal in industrial settings is increased by durability, which guarantees lower maintenance costs and downtime.

 

Analyzing System Efficiency and Pressure Drop

 

Impact on Energy Consumption

One important factor to take into account in fluid control systems is pressure drop. Higher energy usage may result from a significant pressure drop across the valve. Butterfly valves provide three times better flow characteristics than globe valves, which is comparable to 75% of a gate valve of the same size. For any supplier looking to improve system performance, this efficiency is essential because it helps preserve energy and reduce operating expenses.

 

Application Range and Versatility of Valve

 

Flexibility in Various Sectors

The adaptability of Keystone butterfly valves is valued. They are widely utilized in the chemical, pharmaceutical, and food sectors because of their versatility in handling different fluids and their resistance to chemical damage. Their versatility as an on/off and throttling valve increases their usefulness and makes them essential in a variety of applications.

 

Considering Valve Weight and Installation

Easy to handle

A valve's weight is an important consideration when designing its installation and support structure. Lower installation costs are a direct result of a lighter valve. A 10-inch butterfly valve, for instance, may weigh about 55 pounds, whereas a cast iron gate valve of the same size might weigh 490 pounds. Because butterfly valves are lightweight, installation costs are greatly decreased, making them an affordable option for manufacturers in China and elsewhere.

 

Space Limitations and Valve Dimensions

Making the Most of Space

There is frequently a shortage of space in industrial environments. Butterfly valves take up around one-sixth of the space compared to gate valves, which affects plant structure and design. For example, a gate valve with the same diameter is 43 inches tall, but a 10-inch butterfly valve is about 21 inches tall. Placement in confined areas is made easier by its small design without sacrificing functionality.

 

Operational Simplicity and Management

Making Valve Operation Simpler

Butterfly valves simply need to be turned 1/4 turn (90 degrees) to open or close, making their operation simple. Because of its ease of use, general staff can handle it effectively without the need for specialized training. Gate and globe valves, on the other hand, need several turns, which makes operation more difficult. As a result, butterfly valves' ease of use results in lower labor costs and increased operational effectiveness.

 

Budgetary considerations and cost-effectiveness

Cost-effective Valve Solutions

Butterfly valves, which frequently cost only 40% of a cast iron gate valve, provide significant cost savings as compared to other valve types. This financial benefit covers both the cost of purchase and installation. Manufacturers and suppliers can maximize their financial allocation by using butterfly valves, guaranteeing a positive return on investment without compromising performance or quality.

 

Lifecycle Costs and Maintenance Requirements

Providing Durability and Dependability

Maintaining valve function over time requires routine maintenance.  Although EPDM liners are thought to require little upkeep, regular inspections and repairs are required to avoid unplanned malfunctions.  The valve's usefulness in industrial applications is further increased by its easy disassembly and availability of spare parts, which are beneficial for lowering downtime and lifecycle costs.
