Choosing between industrial valves usually comes down to how they are actuated and how they connect into your system. Do you need a simple on/off valve, or a more capable control valve? Answering that decides which of these two fits your line. Both are new open-box units, but they serve different valve jobs.
Quick verdict
The ASCO is the more direct fit for a straightforward line; the Sinclair Collins is the more complete fit for a demanding process application. The decision is less about which one is better overall and more about which one matches the way your valve is powered and mounted.

Where each product wins
ASCO 8215C83 wins on listed price when you want the simpler option. Sinclair Collins SC2000M wins on media compatibility when your line includes steam, hot or cold liquids, air, or inert gas. That media list matters if you are switching a process line rather than a simple air or water service.
Product notes
ASCO 8215C83
Choose the ASCO 8215C83 when you need a 2-way, normally open solenoid valve with a 2-inch NPT connection and a 120VAC coil. It operates within a 0-25 PSI range, which keeps the application simple and direct: energize the coil and the valve shifts, and the normally open design means flow passes when the coil is off. The direct coil action is the main reason to choose it. The limitation is that same pressure range. If your line exceeds 25 PSI, this solenoid valve is outside its stated service, and the 2-inch NPT fitting points toward threaded-pipe installations. You are getting a part intended for low-pressure electrical switching, so if your design assumes a different actuation style, this is not the valve to build around.
Sinclair Collins SC2000M
The Sinclair Collins SC2000M is the choice when the job calls for a position-indicating, air-operated process control valve. Its 316L stainless steel body, floating PTFE seat, and dual bearing guided stem support steam, hot or cold liquids, air, and inert gas, and the DN20 manifold mounting pairs with 1/2-inch ports. The trade-off is installation: the cylinder operator needs 35-120 PSI air, and the valve is designed around manifold-style connections rather than threaded pipe. That makes sense in a process skid but less sense for a simple standalone line. If you need a valve that tells you its position and can handle a wide range of media, this process control valve is the more complete solution between the two.
Final choice by use case
Choose the ASCO 8215C83 for the low-pressure electrical switching job, and choose the Sinclair Collins SC2000M for the pneumatic job. The ASCO is the natural pick for that first use case; the Sinclair Collins is the one to plan around for the second. If you need one valve quickly and simply, the ASCO leads; if you are designing a control loop, the Sinclair Collins gives you more to work with.
