PRODUCT INSTRUCTIONS
40K Multi-Mode Valve (PN 53905/54695)
PI-121
The 40,000 psi Multi-Mode Valve
valve and air-flow regulator. It is to be used in conjunction with the
Jetstream Tornado Gun. The Multi-Mode Valve also controls the quality
and flow of air into the gun's air motor. This tool utilizes a self-contained,
easily-removable cartridge that includes all necessary parts to overhaul
the control valve. The cartridge can be easily replaced in the field within
one minute. The 40K Multi-Mode Valve is rated for operation at 40,000
psi maximum working pressure.
Read these instructions thoroughly before installing, connecting, or using the 40K
MULTI-MODE VALVE. If any questions remain, call JETSTREAM at (800) 231-8192
or (832) 590-1300. Also read the yellow JETSTREAM SAFETY WARNING pamphlet
included with the shipment of your new 40K MULTI-MODE VALVE and reproduced
inside this publication. This product is sold with the understanding that the
purchaser agrees to thoroughly train all operators and maintenance personnel in
the correct and safe installation, operation and maintenance of the product and to
provide adequate supervision of personnel at all times. Retain these instructions
for future reference. If this product is resold or otherwise conveyed, purchaser

  • Page 4 GENERAL WATERBLAST 1. Use only clear, clean water in high pressure system. 2. Place barricades with warning signs or barricade tape around work area. 3. Outfit all operators with Personal Protective Equipment (PPE). Hard hat with plastic face shield, rainsuit, non-skid knee boots with metatarsal protection, gloves, ear protection and body armor rated for operating pressures are considered minimum safety equipment.
  • Page 5 Use wrench flats (when available) or a properly adjusted smooth jaw plier wrench (JS PN 64119) for tightening components. Avoid using pipe wrench as wrench marks will cause high pressure components to crack and fail. 11. All high pressure hose connections require a hose restraint (whip check), including connection at fluid end discharge.
  • Page 6 18. Only trained persons should be authorized to perform any mainte- nance or repair. 19. Following any repairs, the system should be operated at low pressure for test. Bring equipment up to operating pressure slowly. 20. For shutdown in freezing conditions, even for brief periods, drain water from all components.
  • Page 7 3. Prior to use, thoroughly check control gun or control device for smooth and proper operation. Control guns and control devices should also be checked for proper operation before each operating shift. Do not use any control gun or control device that has not been checked before your operating shift.
  • Page 8 13. All electric throttle control cords should be rated for wet conditions. All cord connections and switches should be kept out of water. 14. Any hose used for transporting dump water back to pump should have a large enough diameter and short enough length so that potentially dangerous back pressure is kept low.
  • Page 9 HIGH PRESSURE HOSE 1. Read General Safety section prior to connecting high pressure hose. 2. Do not use a high pressure hose with a burst rating less that 2.5 time the pressure at which it will operate. 40,000 psi operating pressure high pressure must have a minimum 100,000 psi burst rating.
  • Page 10 Use wrench flats (when available) or a properly adjusted smooth jaw plier wrench (JS PN 64119) to tighten nozzle. Avoid using pipe wrench as wrench marks will cause nozzles to crack and fail. 7. Blocked orifice(s) can cause excessive system pressure and failure. If orifice(s) appear clogged or partially blocked with dirt or debris, remove nozzle from MagJet and clean immediately.
  • Page 11 Do not put any piece of repaired equipment into service if its performance is questionable. If repaired equipment performance is questionable, call manufacturer of repair parts for assistance.

  • Page 12: Section 2: Product Description

    Section 6 describes cartridge field replacement. The Multi-Mode Valve is rated for operation at 40,000 psi and features the Jetstream Port Connection for connecting hoses to the valve. Depend- ing on the assembly purchased, hose adapters are included to connect hoses with either type M or HP end fittings.

  • Page 14 Product Configuration The 40K Multi-Mode Valve can be configured in three different modes depending on the equipment used and the needs of the user. Mode is determined by the installation of a nozzle, a plug, or nothing in the mode configuration port.
  • Page 15 2) CONSTANT PRESSURE MODE: For multiple gun operation where system pressure must remain con- stant. This is achieved by installing a properly-sized orifice in the diffuser tube. Releasing gun trigger causes valve to shift from blast gun to fixed orifice, maintaining system pressure. Orifice must be sized using the nozzle selection chart so that its flow is equivalent to the total flow of all the blast nozzles in the attached gun.

  • Page 16: Section 3: Preparation For Use

    3.1 Check the Multi-Mode Valve carefully upon removal from its shipping container for damage. DO NOT use the product if any damage is appar- ent. Instead, notify Jetstream immediately if the condition of any compo- nent is questionable. 3.2 Fill air lubricator with oil per Section 6.2.
  • Page 17 3.7 If necessary, clean cartridge in a mineral-based solvent (diesel fuel, kerosene, paint thinner, etc). 3.8 Clean the control valve body internal cavities and the actuator cylin- der mechanism and cavities, if necessary, to remove all dirt and debris from these areas. 3.9 Apply grease to the external seals and reinstall the cartridge.
  • Page 18 3.17 All frame components should be tight. 3.18 Inlet and outlet connection fittings should be rated for 40,000 psi. 3.19 Inlet and outlet connection fittings should be tight and in good condition. 3.20 The control valve body should be tight on control valve base. 3.21 If intending to operate in Constant Pressure Mode, unscrew the diffuser housing and remove the diffuser.

  • Page 19: Section 4: Setup

    Section 4: Setup 4.0 CONNECTING 40K MULTI-MODE VALVE 4.1 Use only fittings and hose that are related for at least 40,000 psi and have a minimum burst rating of at least 100,000 psi. 4.2 Before connecting the gun and Multi-Mode Valve, all high-pressure hoses should be purged by pumping water through the system to ensure that dirt or other debris does not enter the system and cause damage or overpressurization (plugged nozzle).
  • Page 20 4.6 Consult chart below for replacement or additional components needed to connect Multi-Mode Valves to system. In the chart, Type M fit- tings and hoses for use with valve assembly 53905 are listed first. High pressure (HP) fittings for use with assembly 54695 are shaded in gray.

  • Page 21: Section 5: Operation

    Section 5: Operation Water cleanliness is very important. Use only clear, clean, cold water that has been filtered to a minimum of three microns before the high-pressure pump. 5.1 Use only thoroughly trained operators to perform cleaning operations with the waterblast setup. 5.2 The person controlling the blast nozzle must be the gun operator.
  • Page 22 5.9 With no nozzles installed in the gun or the Multi-Mode Valve, have the gun operator squeeze both triggers to shuttle the Multi-Mode Valve cartridge and direct flow to the gun. Verify that all flow now exits the system through the gun. Also, check the air pressure gage on the Multi- Mode Valve and adjust, if necessary, so that the air pressure through the valve assembly is between 80 psi and 90 psi while the control gun is engaged.
  • Page 23 5.13 Follow instructions for specific mode of operation: CONSTANT PRESSURE and SHUT-IN MODE: 1. With all gun triggers squeezed to engage all guns in the system, unit operator should build to about 1/4 of desired operating pres- sure. 2. One operator at a time, and then both at the same time, should disengage and engage their guns to ensure that the system pres- sure remains near constant.
  • Page 24 (from his location) with the use of a shutdown device (such as Jet- stream’s Emergency Shut-Down Package, PN 53120) if the gun operator encounters problems or if a problem is suspected. Call Jetstream for system specific recommendations. PI-121...
