Disassembly 1. Loosen the handle set screw using an allen key and remove the handle

2. Remove the packing nut & panel nut and set aside for later use.

3. Place the valve bonnet in the panel hole.

Reassembly 4. Tighten the panel nut onto the valve bonnet.

Keep the panel nut always on the external portion of the panel.

5. Finger tighten the packing nut onto the valve body.

6. Place the handle on the stem. Align the set screw with the groove on the side of the stem. Tighten the set screw.

Technical Data Working pressure The class rating and rated working pressure are the way that ASME standards simpllify the design process. The pressure rating is governed by the allowable stress of different material group, class rating, and service temperature.

ASME Material Group Material Name ASME CLASS Rating Temperature @ pressure 100oF (38oC) 200oF (93oC) 300oF (148oC) -65℉ (-54℃) to 350oF (176oC) 400oF (204oC) 450oF (232oC)

V16 Series Severe Service Union Bonnet Valves Pressure Rating up to 6000psig

Catalog No. V16-4 Dec. 2006

Features Pressure up to 6000 psig (413 bar) @ 37℃ (100℉).

High Temperatures up to 300℃ (572℉) with standard PTFE packing; up to 649℃ (1200℉) with Grafoil packing.

Standard S316 stainless steel, optional Alloy 20, and Alloy C276 construction.

Valve stem back seating against the beveled edge of bonnet ensures safety in severe service, this also prevents max. leakage thru. bonnet when a packing fails.

Standard non-rotating stem tip and stem packing below the threads design.

Handle- standard S316 bar handle, optional knob, and Aluminum Bar Handle.

External Packing Bolt- allows packing adjustment without the valve disassembly.

Roll threaded and hard chrome plated stem- is for long valve life.

Panel Mounting Nut- is standard and permits valve to panel or actuator.

Union Nut- prevents accidental disassembly of the valve in service..

Stem Packing below the threads- prevents media contamination and thread lubricant washout.

Back Seating Stem- is blow-out proof design in severe service.

Non-Rotating Stem Tip at Closure- is for maximum metal seat life and positive seal.

Packing Adjustment and Actuation Torque Extreme temperature fluctuations while valve in service may require packing adjustment.

Valves that have not been actuated for a period of time may have a higher initial actuation torque.

Factory Test Every valve is tested with the nitrogen @ 1000 psig (68 bar) for leakage at the seat to a maximum allowable leak rate of 0.1 scc/min. The packing is tested for no detectable leakage. Optional hydrostatic shell test with additional cost is performed with pure water at 1.5 times the working pressure.

Flow Data

Cv are measured at the valve. Therefore restrictions in end connections may reduce flow.

Factory Test

Every valve is tested with the nitrogen @68 bar (1000 psig) for leakage at the seat to a maximum allowance leak rate of 0.1 scc/min. The stem packing is tested for no detectable leakage.

Safety Locking Pin preventing detachment of bonnet from body is vibration tested to MIL-STD-167-1 Pressure boundary wetted parts are selected to Chapter III Material of B31.1, 123 Acceptable Materials.

This valve is designed to ASME B16.34 Class 2500 for pressure-temperature ratings.

Valve ratings are based on ASME code for process piping code B31.3.

To determine pressure rating at 100 F (37 C) in accordance with B31.1 power piping code, multiply by 0.94 for stainless steels.

Operation and Application 2-valve VBR56-2V & VBD56-2V series

3-valve VBR56-3V & VBD56-3V series

5-valve VBR56-5V & VBD56-5V series For measuring flow or level using a differential pressure transmitter or gauge with bleeding, calibration and test functions.

For isolating, calibrating and draining pressure gauges and transmitters

For measuring flow or level using a differential pressure transmitter.

In operation, the block valve is normally open when the bleed valve is closed. To remove the instrument, close the block valve first, and open the bleed valve to relieve pressure upstream of the block valve.

In operation, both block valves are open while the equalizer valve is closed to read a differential pressure to the pressure gauge or transmitter.

To zero the instrument, close the block valve first then open the equalizer valve and zero adjust the instrument.

In operation, both block valves are open while the equalizer and bleed valves are closed to read a differential pressure to the pressure gauge or transmitter. To zero the instrument, close block valves and bleed valve, and open the equalizer valve and zero adjust the instrument.

To remove the instrument, close block valves first, then unscrew the bleeding plug to relieve pressure between the manifold and instrument.

For calibration, connect the bleed port to a pressure gauge to check the calibration of the instrument.

For calibration, by connecting a calibration gauge to the bleed port, able to check the calibration of the instrument without removing it from the installation.

Packing adjustment :

Extreme or rapid temperature cycle may require packing adjustment to maintain a leak-free system.

Tightening the Locknut on the bonnet is for the packing adjustment.

D-Pro V46 series Gauge Root Valves D-Pro Gauge Root Valves offer a safe way of positioning gauges and installing pressure switches.

Design This valve is designed to ASME B16.34 Class 2500 for pressure-temperature ratings.

Valve ratings are based on ASME code for process piping code B31.3.

To determine pressure rating at 100 F (37 C) in accordance with B31.1 power piping code, multiply by 0.94 for stainless steels.

S316 construction with the minimum schedule 160 pipe wall on valve inlet.

Extended body allowing 4.0 inch of pipe insulation.

D-Pro VBV Series Bleed Valves are designed to vent the signal line pressure to atmosphere before an instrument is removed and to assist in calibration of control devices.

These are for use on instrumentation devices such as gauge root valves and multi-valve manifolds.

Optional barbed vent tube enables containment of fluid vented. The VBV Series are also ideal in bleeding hydraulic s ystems.

Position the vent tube so that system fluid is not directed to personnel operating.

Slowly open the valve. This valve has no stem seal packing; s mall amounts of fluid will go through the stem thread when they are opened.

Therefore suitable measures should be taken to protect personnel operating.

Options Bar handle: Optional bar handle allows wrench-less actuation l Bar handle ordering number: BH Barbed Vent Tube: Optional barbed vent tube enables containment of fluid vented. l 3/16"”OD barbed vent tube ordering number: HT To order, use the option ordering number as a suffix to the valve basic ordering number.

Examples: VBV-M-2N-BH-S, VBV-M-2N-HT-S.

Factory Test Every valve is tested with the nitrogen @ 68 bar (1000 psi) for leakage at the seat to a maximum allowable leak rate of 0.1 scc/min.

VPV Series Purge Valves Catalog No. VPV-1 July 20 06

Design D-Pro VPV Series Purge Valves are designed for manually bleeding, venting, or draining system fluids.

The cap is clamped to the valve body for safety in use.

The 0.063 inch (1.6 mm) diameter vent hole is constructed on the cap.

Operation and Installation Instruction D-Pro VPV series purge valve requires a quarter turn of cap with a wrench from finger-tight for a leak-tight seal on the first make-up.

To ensure seal to the rated pressure, snug with a wrench.

Always open the valve slowly.

These valves have no seal on cap. Therefore media may flow through the cap thread when the valves are opened.

Operating personnel should take suitable measures to be protected from system fluids.

Options and How to order Optional PTFE ball is available. Valve with Teflon ball does not require wrench but only finger-tight for leak-tight shut-off.

Pressure rating : 200 psig @ 100 F (13.7 bar @ 37 C) Maximum Temperature : 350 F (176 C) To order, add the valve body material as a suffix to the basic ordering number. S: Stainless, B: Brass. Example: VPV-M-2N-S To order PTFE ball valve, add PE to the basic ordering number. Example: VPV-M-4N-PE-B

Factory Test Every valve is tested with the nitrogen @ 68 bar (1000 psi) for leakage at the seat to a maximum allowable leak rate of 0.1 scc/min.

The valve with PTFE ball is tested at 0.69 bar (10 psi) for leakage at the seat to a maximum allowance leak rate of 0.1 scc/min.
