Medium Flow Pressure Regulators
Our medium-flow pressure regulators are primarily for use on gas service with diaphragm-sensed elements to control up to 10bar (145psi) and piston-sensed elements covering higher requirements up to 414bar (6,000psi). Available in 316SS and brass with the option of parts degreased to G93 for use on oxygen service. Port sizes from 1/2" to 1".
DF1034
Dual-Flow Pressure Regulator: Liquid / Piston / Self-Venting / Max. Inlet: 1,034 bar (15,000 psi) / Max. Outlet: 1,034 bar (15,000 psi) / Cv 1.5 (primary) & 0.06 (secondary)
The DF1034 is a piston-sensed pressure regulator with an incorporated cascaded main valve feature for quick fill of umbilical lines and high pressure water glycol applications up to 1,034 bar (15,000 psi).
Its dual-flow main valve offers a high flow via its primary main valve with a high Cv of 1.5, and the ability to fine tune the control pressure via its secondary main valve with a lower Cv of 0.06.
The DF1034’s design has been considered to descrease pressurisation time and, to ultimately, extend the life cycle of the regulator.

MF101
Medium-Flow Pressure Regulator: Gas or Liquid / Piston / Cone Seat / Self-Venting or Non-Venting / Max. Inlet: 414 bar (6,000 psi) / Max. Outlet: 40 bar (580 psi) / Cv 0.5
The MF101 is a piston-sensed medium-flow pressure regulator. With an unbalanced main valve and non-venting design as standard, the MF101 controls outlet pressures up to 40 bar (580 psi) from a maximum 100 bar (1,450 psi) inlet pressure.
Alternatively, a balanced option can be offered with a non-venting or self-venting (non-captured) design and enables inlet pressures of up to 414 bar (6,000 psi) using a PEEK™ seat, controlling outlet pressures up to 35 bar (510 psi).
