Sanitary Stainless Steel Leak Free Data Center Design Liquid Cooling Energy Storage 3PC Butterfly Valve

Sanitary Stainless Steel Leak Free Data Center Design Liquid Cooling Energy Storage 3PC Butterfly Valve

ONE-PIECE DESIGN NO LEAKAGE FOR TEN YEARS

The adoption of integrated welding technology for valve bodies has revolutionized the tradi-tional bolt connection method.
• Eliminate the risk of valve body leakage;
• The triple sealing ring design ensures zero leakage of the medium;
• With a patented anti-leakage structure, even under abnormal operating conditions, liquid only stagnates within the valve stem sealing chamber, whereas traditional valves may leak from both the valve stem and the valve body joints.
• Commitment to no leakage for 10 years under warranty;
• The sealing performance and durability have been comprehensively upgraded;
• Either end can be disassembled to achieve end face sealing

Technical Specification

The main body of the butterfly valve is made of SS304/SS316L austenitic stainless steel, and the intermediate valve body is welded and integrally formed, which can meet the reguirements of high sealing and cleanliness in biopharmaceutical, food and beverage, petroleum, chemical,steam, liquid cooling, data center, etc.; lt is the first choice for scenarios requiring zero leakage. 
lt adopts the full bore design,which has the characteristics of low fluid resistance, strong corrosion resistance,easy disassembly and assembly，and a total of 4 O-ring seals inside and outside are used at the middle head, which greatly increases the reliability of the butterfly valve seal.

1. Lock nut design
The lock nut device ensures that the sealing ring and self-lubricating are properly seated during valve operation There will be no movement up and down in the letter.
2.EN ISO 5211 flange platform
It is easier to match with the drive at the upper end of the valve. lt can be adapted to turbine head and pneumatic Actuators.
3. Sealing ring
The sealing ring is sealed with two O-rings inside and outside, and the groove width of the sealing ring is the same as that of the O-ring The wire diameter is calculated to meet the fill rate and elongation rate required by the design.
4.Self-lubricating sleeve
The boot is made of PTFE and acts as a guide in the stem.
5. EPDM sealing ring
The sealing ring is made of EPDM material, which meets the national standard of GB/T42268-2022 it works normally under -30° C~100° C medium.
6. Butterfly plate
The butterfly plate is made of austenitic stainless steel forgings, and the material chemical composition meets ASTM A182 Request.
7. Flange
The flange weld is designed according to the 3A ISO DIN standard.
 

Online maintenance

The maintenance can realize non-stop maintenance, the valve is in a closed state, and the 6 bolts of the branch pipeline can be removed under the normal working condition of the main pipeline, and the branch pipeline can be repaired, so as to avoid the risk of secondary leakage and reduce the valve disassembly time.

Testing Standard

1, PED Specification
All butterfly valves according to the European Pressure Equipment Directive (PED) 97/23 EC are manufactured in accordance with PED specifications, and prior to shipment or warehousing, A hydrostatic test must be completed in accordance with ISO5208 international standards Carry out.

2, Escape leaks
J&O valve meets the standard of TALUFT02/27/1986(Pt3.1.8.4) Quasi requirements.
The leakage rate is well below the standard allowable value and Meets the specifications of ENISO15848-2.

3, TS Certificate
Special equipment manufacturing license of the People's Republic of China.

4, Endoleak test
All valves are vented, pressurized, and left closed for testing, And make sure that no air bubbles spill. All ball valves will be vented and pressurized, and the closed position will be tested, during the test no bubbles are generated. All valves comply with class "A"(according to EN12266-1) No bubbles = zero leakage

Mid-head seal structure

Designed in accordance with ANSl B16.34 standard.
(1) The sealing ring is sealed with two O-rings inside and outside, and the groove width of the sealing ring and the wire diameter of the O-ring are calculated to meet the filling rate and elongation rate required by the design. The O-ring is made of EPDM material, which has excellent corrosion resistance,a wide operating temperature range (-40° C to 150° C),high elasticity and compression set resistance, and can still return to its original shape after long-term compression, making it suitable for dynamic sealing scenarios.

(2) The locking nut device ensures that the sealing ring and self-lubricating sleeve are correctly in the sealing box during valve operation, and will not move up and down, and also plays a role in compensating for the gap.

(3) The boot is made of PTFE and acts as a guide in the stem. 

Low temperature properties of rubber materials

TR- is short for Temperature-Retraction, which is specified by ASTM D 1329 and indicates the recovery of deformation in the low temperature range, which is roughly the same as the degree of elastic recovery of rubber. 
The TR10 value represents the temperature at 10% recovery of the predetermined deformation.
