API 607 Fireproof High Performance Butterfly Valve Manufacturer

ZZJG VALVE is API 607 fireproof butterfly valve and high performance butterfly valve, will introduction it, as following:

Before introducing API 607, we first need to understand API. The American Petroleum Institute (API) is the leading standards organization for the U.S. petroleum industry. The API certification system is widely used for equipment in the oil, gas, and chemical industries. API's purpose is to ensure the safety and reliability of oil and gas equipment and to provide globally recognized quality standards. API-approved equipment includes valves (ball valves, gate valves, globe valves, etc.), pipelines and pressure equipment, and fire-resistant and high-temperature equipment. Certification includes the API Monogram Program, which allows authorized companies to display the API mark on their products, indicating compliance with the corresponding API standards.

1.API 6D Valves

Standard Name: API 6D – Pipeline Valves
Application: Ball valves, gate valves, and check valves for oil and natural gas pipelines
Pressure ratings range from ANSI 150 to 2500 lb

Certification Requirements:
Design, materials, and manufacturing comply with API 6D standards
Pressure testing, sealing performance testing, and life testing
Welding, machining, and NDT (non-destructive testing) comply with standards

2.API 600 Gate Valves

Standard Name: API 600 – Steel Gate Valves
Application: Steel gate valves for petrochemical and high-pressure systems
Certification Requirements:
Valve body, disc, and stem design comply with API 600
Pressure testing and sealing performance testing
Material certification and process control records

3.API 607 ​​Fire Protection Certification

Standard Name: API 607 ​​– Fire Test for Quarter-Turn Valves
Scope of Application: Fire-Resistant Ball Valves and Butterfly Valves

Certification Requirements:
Valve must maintain a tight seal under fire conditions
Valve body and seal materials must be high-temperature resistant
Complete flame exposure and subsequent leak testing

Valve Fire Resistance Certification: API 607, API 6FA, and API 6FD

API 607, API 6FA, and API 6FD are important standards for verifying the pressure-bearing, sealing, and operational performance of valves during and after fire exposure. These valves are typically used in applications with potential fire risks, such as the oil, gas, and chemical industries. They are required to maintain a certain level of pressure-bearing capacity, sealing, and operational performance during and for a period of time after a fire.

API 607: Fire Resistance Testing of Quarter-Turn Valves. Scope of Application: Primarily applicable to quarter-turn valves and valves with non-metallic seats, such as ball valves, butterfly valves, and plug valves. Exclusions: Fire resistance testing of transmission devices (e.g., electric, pneumatic, or hydraulic) other than manual transmissions or other similar mechanisms is not covered by this standard.

API 6FA: Valve Fire Test Specification. Scope: Applicable to valves meeting API 6A and API 6D standards, such as ball valves, gate valves, and plug valves. Exclusions: Check valves are not covered by this standard.

API 6FD: Check Valve Fire Test Specification. Scope: Specifically applicable to fire testing of check valves.

In summary, valve fire tests according to API 607, API 6FA, and API 6FD are important standards for ensuring valves maintain their performance in fire environments. Rigorous testing and certification procedures ensure reliable fire resistance in practical applications.

The ZZJG VALVE fireproof high-performance butterfly valve is certified for API 607, 7th edition fire protection. This type of butterfly valve has two seats: a soft-seal main seat made of PTFE/RPTFE, which ensures zero-leakage tight shutoff; and a metal-seal seat that ensures fire protection. This product offers fire protection at a more economical price compared to triple-eccentric metal-seal butterfly valves.

1.Zero leakage: Complies with API 598 zero leakage.

2.Excellent fire resistance and safety in compliance with API607 standards.

a) Double Flanged (ASME B16.34-2009)
b) Butt welded (ASME B16.25)
c) Flangeless Wafer (API 609)
d) Single Flange - Lug type (API 609)
