Safety valves and Relief valves

Safety valves and relief valves are so designed so that the disc lifts automatically when the inner pressure rises to a set pressure, and then closes when the pressure level drops to a predetermined value.
We offer a diverse lineup that supports various fluid types including steam, gas, water, and more.

Safety valves and relief valves protect various equipment from overpressure and are deemed essential for this reason. We have been manufacturing various specialized valves, including the main steam relief valve (SRV) for nuclear power plants and the power control valve (PCV) for thermal power plants.

SRV (Main steam relief valve)

The SRV is designed to prevent excessive pressure buildup inside nuclear reactors and thus plays an essential role in nuclear power plants.
It comes equipped with an auxiliary actuator in addition to a spring, which is its main feature, enabling the valve to be forcibly opened by external operation.

PCV (Power control valve)

PCVs are mounted on the superheated steam lines of thermal power plants. These valves are structurally different from safety valves and relief valves in that they use a magnet instead of a spring to operate.
The pressure sensor detects an electric signal that triggers magnetic excitation, causing the valve to open. These valves can also be opened manually using the control panel.

Pressure Gauges

Hydraulic Pressure Gauge (GP)
The GP model pressure gauges with glycerine filling are particularly suitable for measuring jobs where mechanical vibrations or pressure pulses may arise.

Schaffer Diaphragm Pressure Gauge (SH)
The SH model process gauges is the design principle and material selection of our pressure gauges allow them to meet the stringent demands occurring in service in process industries.

Solid Front Pressure Gauge ( SF)
The SF model solid front pressure gauges are ideal for the hard conditions and the resulting high demands on pressure measuring in production facilities in chemical industry and other comparable branches.

SS Case Bourdon Pressure Gauge (SP)
The SP model process pressure gauges are ideal for the hard conditions

SS Case Capsule Pressure Gauge(SC)
The SC model pressure gauges with Capsule type element are used for measure small positive and negative gauge pressures in gaseous media.

SS Case Electric Contact Pressure Gauge(EP)
The SE model contact presssure with electrical alarm contacts are suitable for controlling or regulating process sequences.
