Springloaded Pressure Regulator Model – GRT8S
Options Many options are available. The most requested options are mentioned below. Materials Regulators can be produced in higher graded materials than stainless steel 316L. Seals
Regulators can be equipped with FFKM + PTFE seals. Other compounds for higher or lower temperatures are available. NACE - MR 0175
All wetted parts of the regulators can be supplied according to NACE MR 0175, including Inconel X750 valvespring and a NACE report.
Captured vent
The thread of the knob-spindel is standard not sealed. The spindel is sealed with the captured vent option. Fluids can be piped away to the vent connection.
Spare parts Spare parts kits are available for the regulator. Mention the serial number in case you need spare parts for existing regulators.
Dependency Character of the regulator is “dependency”. The set-pressure will increase, when you have a decreasing inletpressure. Dependency ratios are listed below. • range 0-20 bar - 1:100 • range 0-40 bar - 1:100 • range 0-100 bar - 1:40 • range 0-280 bar - 1:14 • range 0-420 bar - 1:10 • range 0-700 bar - 1:6
Flow The regulator has good flow performance over the complete range of pressures. Ask for advice if this regulator is the best choice for your application.
Adjusting the regulator The regulator comes standard with a knob. The threadpiece below the knob is designed for frequent adjustment.
Regulators that have a fixed setpoint, can be equipped with a locking cap.

Internals The internals of the regulator are important for the performance. The different internals are mentioned below.
Piston sensing
Piston sensed for all pressure ranges.
Plastic seated
PCTFE is recommended because it seals easy. PEEK is recommended for liquid applications.
Valvespring
The valvespring gives high spring force to ensure seat-tightness.
Filter The regulator can be supplied with an internal filter element to reduce the chances of seat leakage.
Gaugeports The regulator has standard two 1/4" NPT gaugeports to measure the inlet and outletpressure.
Additional gaugeports not available for model GRT8S.

Below ranges are available: 0-4 bar / 0-10 bar / 0-25 bar / 0-60 bar / 0-160 bar / 0-400 bar / 0-600 bar
• case diameter 63 mm• internals ss 316• bottom connection 1/4” NPT
Self-venting The self-venting option provides the possibility to relieve the outletpressure when a decreased setpressure is required. See captured vent option for a sealed knob-spindel.
Self-venting cannot be used as safety valve.
Mounting The regulator can be mounted in every position (horizontal / vertical).
The bottom of the regulator has two mounting holes M5 with 5 mm thread and a C-C distance of 22 mm.

Springloaded Pressure Regulator Model – GRT8S
Connections The regulator has threaded connections, designed for compression fittings.
Line connections NPT threads according to ANSI B1.20.1
Vent connection
The body of GRT8S has a 1/8” NPT vent connection. Do not plug the connection.
For self-venting and captured vent, the vent connection can be used to pipe away the fluid.
Design pressures The design pressure applies for inlet and outletside.
Seat materials The seat materials are related to the design pressure ranges.
PCTFE or PEEK design pressure 420 bar PEEK design pressure 700 bar
Temperature The general temperature range of the regulator is -50 / 200 °C, but is often limited due to the used sealing materials.
PCTFE seat - 50 / 60 °C PEEK seat - 50 / 200 °C NBR seals - 35 / 130 °C FKM seals - 20 / 200 °C EPDM seals - 50 / 120 °C

NACE - MR 0175
All wetted parts of the regulators can be supplied according to NACE MR 0175, including Inconel X750
valvespring and a NACE report.
Spare parts Spare parts kits are available for the regulator. Mention the serial number in case you need spare parts for
existing regulators.
Dependency Character of the regulator is “dependency”.
The set-pressure will increase, when you have a decreasing inletpressure.
Dependency ratios are listed below.
• range 0-1 bar - 1:3000
• range 0-3 bar - 1:3000
The large diaphragm and balanced valve have a
positive effect towards dependency.
Flow The regulator has good flow performance over the complete range. Ask for advice if this regulator is the
best choice for your application.
Adjusting the regulator The regulator comes standard with a knob. The threadpiece below the knob is designed for
frequent adjustment.
Regulators that have a fixed setpoint, can be equipped with a locking cap.

Springloaded Pressure Regulator Model – GRT20S-16
Internals The internals of the regulator are important for the
performance. The different internals are mentioned below.
Diaphragm sensing
The model has a large diaphragm to handle pressures
below 3 bar accurately.
Rubber seated A rubber seat is less sensitive to dirt.
Valvespring and setspring
The valvespring gives high spring force to ensure seat-
tightness.
The setspring is produced according to our high quality specifications. The low spring rate ensures good
performance at high flow.
Gaugeports The regulator has standard one 1/4" NPT gaugeport to
measure the controlled setpressure.
Additional 1/4” NPT gaugeports are available, see option G1 and G2 below.

Mounting The regulator can be mounted in every position
(horizontal / vertical).
The bottom of the regulator
has two mounting holes M6 with 8 mm thread and a C-C
distance of 45 mm.
For regulators installed outdoors, make sure that rain
cannot enter the springhousing or mount it drainable.
