4 EATON Aerospace Group TF100-101D May 2013 The hose end regulator (also known as a hose end control valve [HECV]) is available as Option F in Part 2 (see Ordering Data, page 3 and above). It is designed to limit pressure at its outlet (at the pressure sensing port in the nozzle). The control pressure is a function of the main spring that loads the poppet. In addition to limiting pressure at the outlet, surge and lockup (no flow pressure) are also controlled. Refer to Model 60129-1 catalog sheet (TF10076) for more details on how this is accomplished. The following characteristics are typical: � Normal spring setting (maximum pressure limits will be 5 psi (0.345 bar) greater than spring) — 35 psi (2.413 bar), 45 psi (3.103 bar) and 55 psi (3.792 bar) available � Surge pressure control — 75 psi (5.171 bar) maximum with 0.5 second valve closure (minimum) � Lock up pressure — 10 psi (0.689 bar) maximum over spring setting for 45 psi Option Description Option Description G 2½-inch BSPP female disconnect P Inlet thread — 2-inch NPT H Inlet thread — 2½-inch NPT Q Adds dust cap/plug, camlock type K 4-inch male camlock S 2-inch female camlock L Inlet thread — 3-inch NPT T 2-inch female camlock with locking handle to D1 flange with camlock dust cap M 4-inch female camlock Part 4 Specify the desired thread for a female half, QD or dry break, or to complete the specification of the ball valve outlet. Examples: 64201CEF4HR6H The basic nozzle with 100-mesh strainer (C), vacuum breaker (E), 45 psi (3.103 bar) regulator (F4), 45º inlet elbow (H), interlock bracket (R) standard disconnect (6) with 2½-inch NPT female inlet thread (H) 64201CF5F4U6L The basic nozzle with 100-mesh strainer (C), dual regulators (F5F4) [55 psi (3.792 bar) and 45 psi (3.103 bar) units with the 55 psi (3.792 bar) unit assembled as the one nearest the inlet], stirrup handle (U), standard disconnect (6) with 3-inch NPT inlet thread (L) 64201CF43DEH The basic nozzle with 100-mesh strainer (C), 45 psi (3.103 bar) regulator (F4) (flanged inlet), ball valve (3) with glass viewing port (D), drag ring (E), with 2½-inch NPT inlet thread 64201N Basic nozzle with D-3 inlet coupling that allows the nozzle to be used in either the 45º or straight inlet configuration, as desired (NSN 4930-01-544-1945) Ordering Data (3.103 bar) and 55 psi (3.792 bar) units; 20 psi (1.379 bar) maximum over spring setting for 35 psi (2.413 bar) unit � Pressure limitation — 5 psi (0.345 bar) over spring setting with inlet pressure up to 100 psi (6.895 bar) � Hysteresis (difference in pressure limits between increasing and decreasing flow rates) — pressure limits for decreasing flow rates will normally be slightly greater than for increasing flow rates � Defueling is possible through unit. However, a blockout device is required to maintain maximum flow — use Eaton Model 61656 Blockout Device. � Model 61656 Blockout Device recommended if system secondary control valve is to be checked � The curves shown (right) are typical for the inlet pressures and flow rates shown in a system with appropriate back pressure Pressure Drop Curves The curves presented (below) are typical for the inlet pressures and flow rates shown in a system with appropriate back pressure. These curves are applicable to all Eaton hose end regulator models.
