Mounting Bolt Kits For Modular Valves

Valves are mounted with four stud bolts. Valve combination
varies according to the circuit type. Hence, the mounting
bolt kits are available on a combination type basis.
When ordering the mounting bolt kit, be sure to give the bolt
kit model number from the table below.

Mounting Bolt Kits For Modular Valves

Valves are mounted with six stud bolts. Valve combination
varies according to the circuit type. Hence, the mounting
bolt kits are available on a combination type basis. When
ordering the mounting bolt kit, be sure to give the bolt kit
model number from the table below.
