FRANK PRESSURE CONTROL RANGE

The FRANK plastic pressure control valves and other equipment have been used in South Africa for many years, and have proven to be of the highest quality at reasonable prices.

FAMSYSTEMS offers full advice on the sizes, materials and special operating conditions required.

PRESSURE CONTROL VALVES

Frank offers the following valve range covering a wide range of applications. In all cases the housing is manufactured from PVC, PP or PVDF to cover all possible corrosive duties. In All cases the control mechanisms are protected from corrosive attack by an EPDM or Teflon diaphragm.

• V86: used as relief valve or as pressure maintaining valve. Available in 400kPa and 1000kPa pressure ranges for better control. Sizes from 15NB to 100NB.
• V82 pressure reducing valve maintains the outlet pressure at an even value for feed to sprays, instruments etc. A pressure gauge protected by a chemical diaphragm indicated the out pressure.
• V786 is the more complex version of the V86, with a much flatter curve so that the pressure increase is smaller for large flows.
• V782 is of similar design as the V786 but control the outlet pressure.

CHEMICAL GUARD FO PRESSURE GAUGES

Again available in PVC, PP or PVDF this chemical guard protects standard pressure gauges and pressure switches from chemical attack. Inexpensive when compared with similar Stainless Steel units.

SPECIAL VALVES

• V91, air relief valves in sizes 15NB to 80NB in PVC, PP, and PVDF.
• V95, vacuum relief valve for closed vessels in sizes as the V91.
• V140, all plastic float level valve to maintain level in constant head tanks.
• V251, flow restrictor valve. Needle valve with adjustment screw covered by a threaded cap to reduce possibility of the operator changing settings.

EDUCTOR / VENTURI

A range of standard venturies in size 15NB up to 80NB, in the same materials as above, to add chemicals to a main stream without the need for additional pumps. The removable nozzle allows easy site adjustment if required. As these venturies are standard, costs are relatively low.
