1 Handle operated, metal seated master shut off valve in O-ring seal design for high pressure gas manifold & piping system Exceeds industry standards Provides high flow and resistance to ignition in Oxygen service Easy to operate Robust construction ISO 9001:2008 and TPED certified valve manufacturer

Features and benefits for best-in-class performance Full flow is achieved at two full turns PA 66 thrust washer reduces friction and provides external tightness at high pressure AlSi Bronze upper

2 Features and benefits for best-in-class performance Full flow is achieved at two full turns PA 66 thrust washer reduces friction and provides external tightness at high pressure AlSi Bronze upper stem withstands high resistance against excessive torque Valve body is precision machined in single setup High silicon bronze lower stem provides torsional resistance Valve body and parts are cleaned for oxygen service Non-rotating Monel metal selfcentring seat insert provides positive shut off and reduces seat wear Available in ¾-14 NPT (F), ½- NPT (F) and 1-11 BSP inlet and outlet sizes HEX AF Forged brass T-handle provides adequate leverage to easily open and close the valve under pressure Secondary O-ring prevents moisture / contamination ingress High durometer EPDM back-up ring prevents extrusion of primary O-ring Primary EPDM O-ring provides sealing over entire operating/storage temperature range Metallic seal prevents leakage past packing nut threads Gland O-ring arrests leakage in case metallic sealing is compromised Valve design is successfully tested for resistance to ignition in oxygen service via the filling as well as discharge connection Dimensions are in mm Dimensions shown are for 3/4-14 NPT (F) inlet and outlet Design Specifications MIN life : 2000 cycles Operating and storage temperature range :-40 C to + 65 C MIN closing torque : 10 Nm Packing nut installation torque : Nm Handle retaining nut installation torque : Nm MAX test pressure (TP) : 360 bar Lubricant : Gleitmo 599 Flow co-efficient, Cv : 316 Testing and certification Meets requirements for main valve as per EN ISO 10297:2014, tested by BAM Berlin (ISO VB) Production testing as per EN ISO 14246:2014 Certified by BAM Berlin to European Transportable Pressure Equipment Directive (TPED) and available with mark

3 Operating principle Identifying features BMV-09 is high flow master shut-off (main) valve designed for high pressure compressed gas manifold and piping systems It is suitable for use as a main valve for bundles, tube trailers and cylinder filling panels (filling, venting, vacuum) The O-ring gland seal valve operated by brass T-handle offers smooth operation under pressure Metallic seating ensures positive shut-off and prevents ignition in oxygen atmosphere The upper stem interfaces with lower stem assembly through a square drive The threads are located on the lower stem while the upper stem is free-floating The design uses O-rings to create a seal around the upper stem Polyamide thrust washer makes contact with the collar of the upper stem and acts as anti-friction ring as the upper stem rotates to open and close the valve Recommended opening procedure It is recommended that the valve always be opened gradually in anti-clockwise direction until the required flow is achieved Opening the valve fully causes the lower stem to ride upwards on its threads until it contacts the upper stem collar As the valve in the fully open position can be mistaken as closed by inexperienced or untrained operators, operator should always check the position of the valve by attempting to close the valve, never by trying to open the valve Recommended closing procedure Close the cylinder valve by rotating the T-handle in the clockwise direction 1 Valve is not suitable for Acetylene service (refer list of gases for which the valve is qualified) 2 NEVER use wrenches or other persuaders to operate the valve

5 Disassembly, inspection and assembly instructions Disassembly of valve 1 Place the valve assembly in a vice or similar holding fixture The holding fixture must securely grip the valve body (1) on the wrench flats so that there is no damage to the valve body, inlet and outlet threads 2 Using 17 mm HEX box spanner, unscrew the handle retaining nut (10) by turning it counter clockwise 3 Remove the T-handle (8) from the upper stem (3) square The plain washer (9) will come out with the handle 4 Using an 35 mm socket wrench or HEX box wrench, unscrew the packing nut (7) in counter clockwise direction The upper stem assembly with thrust washer (4), O-rings (6) and back-up ring (5) will come out with the packing nut Remove the upper stem from the packing nut by pushing the upper stem from the top Be careful not to scratch the packing nut sealing surface 5 Dismantle thrust washer, O-rings and back-up rings if required 6 Use the upper stem to remove the lower stem assembly (2) from the valve chamber, by rotating it counter clockwise Inspection of valve body and components 1 Valve body (1) a Inspect the valve body chamber for dirt, debris or damage Where possible, blow out the valve body chamber using clean, dry, compressed Air or Nitrogen to remove any foreign particles b Inspect the valve body for seat damage and thread wear c Inspect if gland O-ring (11) is in place inside the valve body groove d Do not attempt to repair the valve body if damaged 2 Components a Inspect all parts visually for wear, damage Replace parts as necessary In case of damage to upper stem (3) and / or elastomers, replace upper stem assembly b Inspect lower stem threads and seat insert (2) for significant signs of wear / damage Inspect the thrust washer (4) Replace lower stem assembly if necessary Assembly of valve 1 Lubricate parts as per GA drawing NOTE Customer will receive parts / spare kits in lubricated condition 2 Place thrust washer (4) to rest above the upper stem (3) collar 3 Use special tools to fit O-rings (6) and back-up ring (5) in upper stem groove Care should be taken to place the back-up ring above the O-ring in the lower groove and secondary O-ring in the upper groove 4 Fit gland O-ring (11) inside the groove provided in the valve body (1) just below the packing nut (7) threads 5 Insert upper stem assembly inside packing nut with a twisted motion to avoid damage to elastomers and push till it rests on packing nut counter bore 6 Place the lower stem assembly (2) into the valve body Position the upper stem to engage with the lower stem square and screw in packing nut into the valve body by rotating the upper stem square This will also drive the lower stem assembly to rest with the valve body seat 7 Clamp valve body in bench vice between nylon clamps Tighten the packing nut to Nm in clockwise direction 8 Place T-handle (8) on the upper stem square 9 Place plain washer (9) and tighten handle retaining nut (10) to Nm to secure the handle NOTE Refer Material of construction and assembly arrangement page to identify the part No given in the bracket Last updated: 22 nd March, 2016
