Valves

• Convenient method of blocking, bleeding ,and calibrating pressure instruments
• Designed for connected system impulse line & transmitter
• Combine the function of a tee, calibration valve,isolation valve,all tubing and fittings in a single valve configuration

• Free swiveling ball end stem (metal seat,std.)assurance bubbles tight valve closure without seat galling
• Special hardened ball seat is ideal for both gas and liquid service
• All stem packing is located below the stem threads preventing galling corrosion and contaminations
• Adjustable packing reduces the possibility of bonnet/body leaks
• Full back -sealed bonnets prevents accidental stem removal and blowout

• Orifice Size :0.156inch (4.0 mm)
• For block and bleed (or calibration) of a gauge -or absolute -pressure transmitter or gauge
• Consists of equalizing , isolation and vent
• Direct instrument mount and remote mount
• End connections 1/2 pipe or flange

Type Applications

• General plant service
• Pressure instrumentation devices
• Differential pressure instruments devices
• Pressure equalitzation
• Block and bleed applications.

T-Type (single flange, pipe to flange)
Manifolds bolt directly to the differential pressure instruments which eliminate the need for unnecessary piping,valves and fittings.T-Type manifolds come complete with mounting kit for quick and easy installation to a pipe stand.

R-Type valve Designs
R-Type (pipe to pipe in-line )manifolds are designed for differential pressure of flow recorder to impulse tubing.Connections are 1/2" NPT industry standard and 2-1/8" (54 mm)center dimension( Model for 2 3/16" & 21 /4" dimension(Model for 2 3/16" &21/4"-center dimension.

H-Type (Dual flange, flange to flange)
Manifolds bolts directly to the differential pressure instruments which eliminate the need for unnecessary piping,valves and fittings.

• High accuracy
• Rugged in performance
• Robust designing

• Rugged construction
• Corrosion-resistance
• Durability

• 6000psi (414 bar)gas and super heated steam at 1,100°F (593°C)
• Excellent flow characteristics
• Allows streamlined flow
• Eliminates corrosion and deposits 6 0°incline pressure drop

• Tight shutoff
• Long valve life
• Prevents corruption
• Easy re-facing Positive seating function as standard
• Seat is guided at bottom and top Integral STELLITE Gr.6 deposited with specialized and automatic procedure which guarantees the achivement of stated constant characteristics
• The deep thickness of the deposited STELLITE Gr. enables many renewing operations of the seating surface

• Non-rotating solid cone eliminates galling
• Eliminates scoring or bending of the stem No torsion applied to gland packing
• Easy on site maintenance and low maintenance cost Low operational torque
• Can not be detached from the stem Close roundness and straightness tolerances
• Burnished for superior finish

• Graphoil as standard maximum temperature 650 degree C.
• Long operating life Prevents corruption

• Withstand high stresses caused by liveloading Bolt torques control total spring load Two sets of GLAND BUSHINGS maintain a minimum permanent stress of 4000psi on the graphite packing keeping it tight for long periods of time without maintenance

• A lantern ring and leak-off pipe provide detection or removal of leakage, if any, from the lower packing set

• Sealing effectiveness improves as overall packing length shortens.
• Chamber wall is burnishhed to a superior finish

• Of nodular cast iron Its form allows positive grip Impacted Hand-wheel is not necessary thanks to the two roller beatings.

• Well lubricated stem nut rotates on two thrust bearings 10,000 test cycles show no visible damage to parts Dust cover and sleeve protect stem threads from dirt, dust and sand

• STORAGE ON SITE Do not remove end protectors until ready to install Store valves indoors in a well- protected, dry area. Do not store in contact with the floor. Store on pallets or Shelves.

• Remove end protects when ready to install. Check nameplate to ensure correct type of valve. Valves should be partially open during welding. If the valve will be normally closed, piping should be flushed, the valve should then be operated 2-3 times before finally seating to prevent solid particle remaining between the seat and disc.

• Inspect periodically all critical parts for wear steam threads. Packing and packing glands. Body-bonnet joint and bolting seats.
