The Ham-Let® H-700 Series is a moderate-pressure ball valve for general service.
These valves are compact in size and structure. They have relatively large ports for high flow, tight shutoff, long-life service, and low operating torque.
The H-700 Series can be used for bi-directional flow in fully open or fully closed position only. The series is rated to maximum 2000 psig (135 bar) and performs on/off service.
Testing:
- The H-700 design has been tested for Burst and Proof.
- Each H-700 valve is factory tested with nitrogen at 1000 psig.
- Maximum allowable leakage across seat is 0.1 std cc/min.
Packing Adjustment:
- Due to the varied service applications of the valve, packing adjustment may occasionally
be necessary.
- Packing is factory adjusted to 1000 psig service. Initial packing adjustment is recommended after installation and prior to start-up.
- Please find more information on H-700 under Installation Instructions.
Ham-Let® Ball Valves are designed for operation in the fully closed or fully open position.
