Product Information

INTRODUCTION

Over 40 years, we have been supplying a variety of safety relief valves to satisfy the highly variable
requirements of customers.
JSV-FF100 as representative safety relief valve of Jokwang is designed and produced based on the
accumulated technology of long experience.
We strongly recommend JSV-FF100 to protect overpressure of the vessel and process line using in the
various industries.

APPLICABLE CODES, STANDARD and AUTHORIZATIONS
The JSV-FF100 series is compliant with the following codes and standards.

  • ASME SEC. VIII
  • RELIEVING CAPACITY tested & certifi ed by NBBI
  • API RP 520 / SIZING, SELECTION AND INSTALLATION OF PRESSURE-RELIEVING DEVICE IN REFINERIES
  • API RP 526 / FLANGED STEEL SAFETY-RELIEF VALVES
  • API RP 527 / SEAT TIGHTNESS OF PRESSURE RELIEF VALVES
  • ASME B16.34 / VALVES – FLANGED, THREADED, AND WELDING END

DESIGN FEATURE

Certifi ed Discharge Capacity
JSV-FF100 is designed and manufactured in accordance with ASME Sec.VIII.
Also the discharge capacity is certified by NBBI(National Board OF Boiler and Pressure Vessel Inspections) as well.

Excellent Seat Tightness
Disc construction of JSV-FF100 is composed of a disc and disc holder.
This kind of simple shaped disc permits a uniform pressure distribution not to make any distortion of seat, thus maintaining excellent seat tightness.
In addition, the seat is machined and lapped with a high precision to enhance the seat tightness.

A Single adjusting ring applied
A single adjusting ring is used to minimize the simmer phenomenon and initial lifting force for the clear popping and blow down.
In case of double ring type could be obtained the full lift, also the fixed holder of single ring type can function as upper adjusting ring of double ring type. Because of that the single ring type could insure full capacity under the condition within 10% overpressure.

International Code applied
Length(center to face dimension), Flange, Size and Pressure & Temperature limit are in accordance with the international standard.

JOKWANG was registered on the KOSDAQ market as a venture company in 2001. We are the only one special valve maker registered on the KOSDAQ in Korea until now. Korea Government (Ministry of Knowledge Economy) had selected JOKWANG among the safety valve makers in Korea to localize the MSSV(Main Steam Safety Valve) for Nuclear Power Plant in 2002. With financial support of Korea Government, we have tried to localize it for a long time and then it was developed in 2006. At present time, we have been developing the Cryogenic Safety Relief Valve for LNG/LPG service. In 2006, we have acquired ASME Sec. VIII "UV" STAMP. In 2010~2011, The expansion of "UV" stamp range is succeed by NBBI authorized test laboratory under ASME. (Pressure : up to 6000psi, Addition : Liquid, Bellows type)
