Valves for industrial refrigeration
We extend our product range with valves for industrial refrigeration. Thanks to our permanent stock in Toulouse, France, we can deliver with short lead times.
Our partner DoFun (ShanDong DoFun Refrigeration Technology Co., Ltd) has established itself as a leader in its domestic market. On the strength of this position, it is developing its export business with partners renowned in their respective markets.
Design, manufacturing quality, flexibility and responsiveness, R&D and cost control make it a first-choice supplier.
A flexible product family
Various function modules can be added to a standard straight or angled body:
- stop valve
- long-stem stop valve
- hand-regulator
- check valve
- stop-check valve
- filter.
This family is available in PN40 and PN63 bar for the carbon steel version and PN63 bar for the stainless steel version. The bodies have a different colour depending on the PN, and the colour of the cap or function wheel makes it easy to distinguish the different functions.
Pilot-operated servo valves
Servo-piloted valves are essential control components in refrigeration systems. They are mainly used to regulate upstream, downstream or differential pressure without a PLC.
They consist of a body, a function module and a cover carrying the functions.
The pilots that can be fitted are :
IPV: regulates an upstream pressure (inlet);
OPV: regulates outlet pressure;
DPV: regulates differential pressure;
EPV-NC: NC solenoid valve;
EPV-NO: NO solenoid valve;
PHV: combination of IPV + EPV;
EPC: connector for external pressure;
plug A: plug leaving the pilot channel open;
plug B: pilot channel blanking plug.
Small valves
A range of small valves in DN6 and DN10, PN40 and PN63 bar, in carbon steel or stainless steel, makes it easy to fit instrumentation to refrigeration systems. A wide variety of connections are available.
Other valves
In addition to the basic taps, we offer several other types of tap. This range will be expanded gradually.
