trailer control valve , Iran

The trailer valve, or Emergency Shut-off Valve, is constructed from A356-T6 aluminum alloy or carbon steel. It is designed for a working pressure of 250 PSI approximately 17 bar. The connection diameter is typically 2 or 3 inches with NPT or ACME threaded standards. Its full closure time under nominal pressure is less than 3 seconds. The primary seal uses a resistant elastomer like Viton or EPDM with a -40°C to +120°C operating range. The valve features a manual activation mechanism and a pneumatic actuator requiring minimum 60 PSI air pressure. Its hydrostatic testing complies with DOT-406 standard at 375 PSI.

The internal structure features an axial shut-off disc with a 304 stainless steel stem. The required force for manual activation is under 150 Newtons. The valve body includes a chamber for installing a position switch. This switch transmits the open/closed status signal to the cabin. All wetted parts are resistant to petroleum-based products. The valve has a minimum IP67 rating against water and dust ingress. This design allows rapid isolation of the cargo tank from the vessel in emergencies and complies with DOT and ADR regulations.You can order and buy trailer control valve from Iran by contacting us through whatsaap and email.
