Pertanyaan yang Sering Diajukan
Pertanyaan umum tentang PLAST-O-MATIC dari 3G Electric.
What materials are PLAST-O-MATIC valves and flow indicators available in?
PLAST-O-MATIC components are primarily manufactured from PVC and polypropylene. PVC models are suitable for a broad range of chemicals and offer a maximum operating pressure of 140 psi. Polypropylene models provide higher temperature resistance and are rated to 115 psi. Both materials resist corrosion from acids, bases, and many solvents. Seals and diaphragms are typically FKM (Viton) for chemical compatibility. Window materials on sight flow indicators are acrylic.
What is the difference between single-wall and double-wall sight flow indicators from PLAST-O-MATIC?
Single-wall sight flow indicators have one acrylic window for direct viewing of the fluid. Double-wall indicators have two concentric windows, providing an additional containment layer in case the inner window fails. Both types are rated for horizontal mounting and can be installed in any flow direction. Double-wall models are recommended for hazardous or high-value fluids where leak prevention is critical.
Are PLAST-O-MATIC solenoid valves suitable for outdoor or washdown environments?
PLAST-O-MATIC solenoid valves are available with coil enclosures rated as dust-tight or watertight. For example, the PS series with watertight enclosures can withstand direct water spray and dust ingress. Standard models without junction boxes are intended for indoor or protected locations. Always verify the coil enclosure rating against the environmental conditions of the installation site.
What pipe sizes and connection types are available for PLAST-O-MATIC check valves?
PLAST-O-MATIC inline diaphragm check valves are available in pipe sizes from 1/2 inch to 2 inches, with FNPT x FNPT threaded connections. The diaphragm design provides low cracking pressure and positive sealing against backflow. These valves are suitable for vertical or horizontal installation and can handle flow in any direction.
Can PLAST-O-MATIC flow indicators be used with opaque or dirty fluids?
PLAST-O-MATIC sight flow indicators are designed for clear or translucent fluids where visual observation of flow is possible. Opaque or heavily contaminated fluids may obscure the view through the acrylic window. For such applications, alternative flow monitoring methods such as flow switches or ultrasonic sensors should be considered.
