Most common and varied types of control valves are globe valves and angel valves. Their validity includes a strong structure and having many options that make them suitable for the use of various processes, including services. The body of control valves can be in the following cases:
- Angle Valves
- Cage-style valve bodies
- Disk Stack style valve bodies
- Angle seat piston valves
- Globe valves
- Single-port valve bodies
- Balanced-plug cage-style valve bodies
- High capacity, cage-guided valve bodies
- Port-guided single-port valve bodies
- Double-ported valve bodies
- Three-way valve bodies
- Diaphragm Valves
- Rotary valves
- Butterfly valvebodies
- V-notch ball control valve bodies
- Eccentric-disk control valve bodies
- Eccentric-plug control valve bodies
- Sliding cylinder valves
- Air-operated valves
Pressure safety valve:
– About the safety valve
In the case of a safety valve, one of the types of valve is that when the inlet pressure of the valve increases to a predetermined pressure, it is automatically activated to open the valve disk and drain the liquid (steam or Gas), and when the pressure drops to the value previously specified to close the valve disc again.
The safety valve is basically installed in a chemical device, electric power boiler and gas storage tank and prevents the explosion or failure of pressure vessels.
– Safety valve function
1- The “opening” inside the valve starts to receive pressure higher than the inlet side of the valve.
2. When the pressure exceeds the set pressure, the “disk” begins to rise and drain the liquid.
3- When the pressure drops to the predetermined pressure, the force of the spring disc closes.
The role of spare parts:
Spout — Pressure inlet
Disk — Valve
Spring — pressure controller
Classification of safety valves:
There are three types of safety valves: FUKUI in the production line
:Spring-Loaded Pressure –relief Valves –
Indicates that it is the most common type. (Image Spring-Loaded Pressure – Relief Valves
See) .Spring bar is designed to compress the disc against the inlet pressure. Depending on the type of liquid, such as steam, gas or liquid, we recommend the following model to clear the effect of back pressure:
:Pilot-operated Pressure-relief Valves –
Spring-Loaded Pressure-relief Valves This type of safety valve is a combination of a pilot test and a main valve.
Pilot-operated Pressure-relief Valves Accepts spring against inlet pressure, pressure reduction and reset pressure
No settings on the Spring-Loaded Pressure-relief Valves are controlled by the sensing pilot, which is almost like
Spring-Loaded There are no larger sizes compared to the original Pilot-operated Pressure-relief Valves.
Special service options such as high pressure are being offered.
:Dead-Weight Pressure-relief Valves –
Reduce pressure only by Dead-Weight Pressure-relief Valves according to the design of pressure vessels as very low pressure
Adjusts disk weight.
The vacuum valve absorbs the pressure when the inlet pressure of the arteries drops to a negative pressure.
