Valtek® Mark Eight Linear Angle Control Valve
The Valtek Mark Eight linear angle control valve uses a Y-style body to create a more direct flow path than conventional globe valves. The design delivers higher capacity with less turbulence, while clamped-in seating and interchangeability with Mark One components support tight shutoff and economical maintenance.
