There are several variations on the channel for soft seal plug valves. Generally, the fluid is truncated using the typical through-through type. Fluid reversal can be done with three-way and four-way plug valves.In order to open and close the channel, the cock valve's opening and closing component is a cylinder with holes that rotates around an axis perpendicular to the channel. Using soft seal plug valves, pipes and equipment media can be opened and closed.
Application scope of soft seal plug valve:
Soft seal plug valves are frequently employed in corrosive, extremely toxic, and harmful media as well as other hard environments. It is strongly forbidden for these valves to leak on these occasions, and the valve material won't pollute the media. The working medium might dictate whether carbon steel, alloy steel, or stainless steel should be used for the valve body.
The main construction features of JLPV plug valve are following:
1. Suitable for frequent operation, opening and closing quickly, light.
2. Soft seal plug valve fluid resistance is small.
3. Simple structure, relatively small volume, light weight, easy maintenance.
4. Soft seal plug valve sealing performance is good.
5. Not limited by the installation direction, the flow of the medium can be arbitrary.
6. No vibration, low noise.
The range of JLPV plug valve design is as follows:
1. Size: 2” to 14” DN50 to DN350
2. Pressure: Class 150lb to 900lb PN10-PN160
3. Material: carbon steel, stainless steel and other common metal materials.
NACE MR 0175 anti-sulfur and anti-corrosion metal materials.
4. Connection ends: ASME B 16.5 in raised face(RF), Flat face(FF) and Ring Type Joint (RTJ）
ASME B 16.25 in screwed end.
5. Face to face dimensions: conform to ASME B 16.10.
6. Temperature: -29℃ to 180℃
JLPV valves can be equipped with gear operator, pneumatic actuators, hydraulic actuators, electric actuators, bypasses, locking devices, chainwheels, extended stems and many others are available to meet the customers’ requirements.
