2022年1月4日 · Common rubber valve seat materials include EPDM rubber, nitrile rubber (NBR), and PTFE. What is EPDM seat? EPDM rubber: EPDM is the abbreviation of Ethylene Propylene Diene Monomer. Compared with other general rubbers, EPDM rubber is very cost-effective.

Two of the most popular seat materials—BUNA-N and EPDM—are commonly used in industries ranging from food and beverage to biopharmaceutical. Below, we’ll explore the essential differences, typical chemical compatibilities, and the main pros and cons of each, helping you determine which seat material best meets your facility’s needs.

2022年8月8日 · Common non-metallic materials for butterfly valve seats include EPDM, NBR, and PTFE. This article mainly introduces the material information of different valve seats. If you need to buy EPDM/NBR/PTFE seated butterfly valves or more information, please contact VALTECCN butterfly valve suppliers and manufacturers business.

EPDM is a standard seat material offered in Bray resilient-seated butterfly valves. It is the most universal and economical of seat materials offered by Bray; that is, it may be used in a wider range of applications than BUNA-N (hydrocarbons are EPDM’s main Achilles’ heel.)

1 天前 · Butterfly Valve Seat Material Selection. The performance of a butterfly valve is not only determined by its body material but also heavily depends on the seat sealing material. In the face of various fluid challenges, materials like EPDM, NBR, PTFE, and VITON act as precision-engineered "soft armor," forming a robust barrier that ensures ...

Below is a general butterfly valve seat selection guide. When selecting seats, always consult the pressure / temperature charts and corrosion resistant guide or contact the factory for engineering help. Rated for temperatures -30°F to 250°F. EPDM is an abbreviation of a compound called Ethylene Propylene Diene Monomer.

2021年1月7日 · EPDM is ideal for processes that involve water, alcohols, bleach, glycols, ketones, phosphate, esters, chlorine, and other alkaline solutions. EPDM temperature rating range is -30ºF to 225ºF. EPDM is widely used in HVAC systems.

In the realm of valve technology, selecting the right seat material is pivotal. NBR (Nitrile Butadiene Rubber) and EPDM (Ethylene Propylene Diene Monomer) are two popular choices for butterfly valves, including wafer type, lug style, sanitary, stainless, and electric variants. NBR’s oil resistance contrasts with EPDM’s superior weather resilience.

Guide on selecting the best seat material. Proper valve seat material selection enhances system reliability, ensures optimal flow control, and prevents costly leaks. ... EPDM seats have a temperature range of around -40°C to 120°C. Buna-N: Buna-N, also known as nitrile rubber, is a multi-purpose rubber that has high strength and abrasion ...

2021年8月30日 · The butterfly valve seat is made of a wide range of materials, but the commonly used materials include soft-seal EPDM, nitrile rubber (NBR), polytetrafluoroethylene (PTFE), and metal hard-seal hard alloy materials. kind. Let’s introduce them one by one below. 1. EPDM: Compared with other general-purpose rubbers, EPDM has great advantages.
