*NEW PRODUCT* C-T50 REGULATOR

DESCRIPTION

The C-T50 is a two-stage, primary and secondary regulator for LP-Gas using vapor withdrawal

for stationary and mobile engine application. Some models are supplied with a built-in vacuum

controlled 100% shutoff when engine stops. The C-T50 regulator has an idle fuel adjust for fuel

mixtures for starting in place where a separate idle line is not needed. Manual primer on back

cover is optional.  A fuel filter is recommended for this unit.

The Century model C-T60-N-2L has been reverse engineered to replace most Nikki regulators for field replacement. The back cover has 2 mounting lugs with the same dimensional pattern as the Nikki regulator. Water, fuel out location, and thread sizes are the same. Vacuum port in the Nikki regulator has a pressed in fitting where Century's regulator will need a fitting installed to accept a vacuum hose. Standard thread size in the Century regulator is 1/8' NPT with either a 3/16' or 1/4' NPT I.D. hose size/90 degree elbow fitting.

 6 PSI, W/ VACUUM LOCKOFF DIAPHRAGM, NO PRIMER

Note: All units have tamper caps included, per CARB,  for primary pressure adjustment and idle adjustment area. Tamper cap to be installed at idle area  by the approved installer once final fuel mixtures are set on site. Units have primary pressure settings pre-set at the factory at 6 PSI.

Description

The C-MR-1, C-MR-1-AH, C-MR1-I, C-MR1-I-P, C-MR1-AH-I, & C-MR1-AH-I-P regulators are a compact two stage double diaphragm type regulator

designed specifically for use with small air cooled engines. It combines both primary and final

secondary stage regulator into a single compact unit. The regulator is simple to mount on any

engine size up to around 28 HP by means of a multi-purpose type bracket. The C-MR-1

regulator uses vapor fuel and the C-MR-1-AH can used liquid with the fins mounted next to a

heated exhaust area. The fuel inlet received fuel from the fuel tank and the fuel out flows to the

carburetor or adaptor.

Operation

Vaporized fuel is admitted to the regulator inlet at tank pressure (up to 250 psi). Since the

secondary valve is closed, the pressure on the internal side of the primary diaphragm builds up

until it overcomes the spring acting on the other side of the diaphragm. The primary valve is

held open by the primary diaphragm spring until the pressure in the primary chamber reaches 2

to 3 psi, at which point the force on the diaphragm balances the spring force and closes the

valve. The secondary diaphragm, actuated by vacuum obtained from the carburetor or

adaptor acts against the secondary valve spring. As this vacuum begins acting on the

diaphragm, the diaphragm is moved nearer the center of the regulator, opening the secondary

valve. As more fuel is required, vacuum from the carburetor or adaptor increases, causing the

secondary valve to open further, admitting more fuel. When fuel is flowing, the pressure on the

primary diaphragm is lowered slightly, permitting the spring to open the primary valve to

attempt to bring the pressure back to 3 psi..
