GATE VALVES

DOUBLE SEALING RESILIENT GATE VALVE

Double Sealing Resilient Seated Gate Valve for Water Works is the world best valve that usage data of hundreds full bloom proves the quality for several decades. It was proved the quality and performance because have used hundreds full bloom in van Europe every country since was developed by first in European Hawel 40 years ago. Samjin Precision Co., Ltd makes as the quality.

ATTACHED AIR VENT TYPE, RESILIENT SEATED SLUICE VALVE AND GATE VALVE DOUBLE SEALING RESILIENT SEATED GATE VALVES WITH PRESSURE GAUGE   FEATURE Attaching a pressure gauge to resilient seated gate valve has these advantages. 1. The data from checking the water pressure occasionally by sections and regions can be used in 1. solving the unbalance problems in water pressure among regions. 2. Whether there has been a water leakage or not can be detected from checking whether there was a 1. decrease in water pressure after closing both sides of the gate valves in certain sections. 3. A sample of water quality can be collected through the attachment holes FORMATION 1. Structure ① Valve: resilient seated gate valve ② Ball valve: KS Standard size Ball valve 2. Size 65, 80(75), 100, 125, 150, 200, 250, 300, 350, 400, 450, 500mm ※ Caution: Avoid exposure to the sun when keeping in custody KNIFE GATE VALVE EXTENSION SPINDLE RESILIENT SEATED SLUICE AND GATE VALVE FIXED TYPE              ADJUSTABLE TYPE   FEATURES 1. This is exclusive valve for under ground laying. 2. Easy peration and see the location of key cap for gate valve flowing in soil, water and dust etc. 3. Prevention a mishap of valvel by forced using of stem and easy operation owing to strong supporting 1. point in the top. 4. Be economical, No need a protection box(FRP) and pipe(PVC) of gate valve separately in using iron 1. cover manufacuuring in one piece with gate valve. 5. Maintenance cleanly without rust by the same fusion bonded epoxy powder coating as gate valve   STANDARD MATERIALS 1. Connection Joint : Ductile Iron 2. Stem : Stainless Steel 3. Extension Spindle : Steel 4. Protection pipe for Extension Spindle : Steel 5. Bushing : Brass Bar 6. Bolt : Stainless Steel 7. Painting : Fusion Bonded Epoxy Powder Coating   SPECIFICATIONS 1.Fixed and Adjustable Types 2.Applicable Size : 50 - 500mm   BEFORE AFTER ATTACHED CHECK VALVE TYPE, RESILIENT SEATED SLUICE   FEATURES 1. Prevention any containments flowing in from main pipe occured stauing water as stay for a long 2. time in pipe line 2. Can be economized a water resources by minimum of thrown water quantity for washing of pipe 2. line. 3. Can be minimized a flow loss. 4. Can be installed without water suspension of water supply. 5. No rust by fusion bonded epoxy powder coating.   STANDARD SPECIFICATIONS 1. Resilient Seated Sluice valve : 80 ~ 200mm 2. Poppet Type spring check valve : Bronze and Stainless Steel 3. Concentric Taper : Ductile Iron   APPLICATION   Prevention of staying water Prevention of waste and containment Prevention of flowing backward Interception of water impact Prevent any pollution flowing in form main pipes oeoured staying water as slay for along time between hydrent and main pipe. Prevent water pollution beforetrand inter cepling inflow of main pipe of degenerated wate. Prevent water mater and exect mesauring as check flowing beckward from the hily sections and watertank of the roof. Provent pump from occurod water impact by water beckward SJV BS 5163 DUCTILE IRON, RESILIENT SEATED SLUICE VALVE AND GATE VALVE       RESILIENT GATE VALVES FEATURES Former gate valves were hard to use because tools like tongs had to be used when being installed and extraneous matters such as sand would flow into the gate valve protection box due to the short valve shaft. However, we managed to complement this demerit of our gate valve protection box and made the valve shaft longer in order to make the valve shaft to open and close directly without using such things like tongs and to be smoothly used regardless of the extraneous matters inflow such as sand.   FORMATION 1.
